How to Earn Free Bitcoin
Bitcoin is a real hype on these days. Everyone is talking about Bitcoin. If you are looking for a way to earn Bitcoin…
Bull Market — A prolonged upward trend of a traded commodity. This is the opposite of a bear market.
Casper — The Proof of Stake algorithm that Ethereum will implement with the release of the Serenity update.
Cold Storage — Storing crypto away from the internet. Meaning on a paper wallet, in a hardware wallet, or on an air-gapped machine.
Confirmation — A transaction is confirmed when it has been verified by miners on the blockchain.
Correction — A correction is a reverse movement, usually negative, of at least 10% in a stock, bond, commodity or index to adjust for an overvaluation. Corrections are generally temporary price declines interrupting an uptrend in the market or an asset.[Source — Investopedia]
Day Trading — The practice of actively trading your assets. A day trader is also known as an active trader.
Dollar Cost Average(DCA) — Placing a fixed amount towards an investment every month on a regular basis.
Exchange — Where you buy and sell your traded commodity. In our case: GDAX, Poloniex, Kraken, etc.
The Flippening — The point at which Ethereum’s market cap overtakes Bitcoin’s.
FOMO — Fear of Missing Out. This is a term used to describe the act of purchasing a commodity while it is on a bull run. It often carries a negative connotation, in that FOMO may cause the price to be artificially high and indicate that a correction is coming.
FUD — Fear, Uncertainty and Doubt. This term is used to describe the malicious spread of negativity. This is often done with the goal of causing inexperienced members to sell, or possibly cause a temporary dip in price.
Hardware Wallet — a cryptographically secure piece of hardware designed to keep wallet information secure. E.g. Trezzor wallet, ledger nano, etc.

Margin Short (Shorting) — This is the act of selling something that you’ve borrowed with the hope of being able to buy it back later at a lower price. [Source — Investopedia]
Margin Trading — Trading on money that has been loaned to you by an exchange. A deposit of capital must be placed to receive said loan.
Market Order — Placing either a buy or a sell order on the market with no regard for price. The market will buy or sell $x.xx/yy eth, for the best price currently available.
Metropolis — The third of four major phases of Ethereum. Characterized in part by improved anonymity of calculation validation. Explained in more detail below.
Paper Wallet — A printed document containing the information linked to your wallet. I.e. your private key, public key, etc.
Private Key — This is like the key to your home. It can unlock your wallet and everything inside it for whatever transaction you (or whoever has it) choose. It is not advisable to share this with ANYONE.
Proof of Stake (PoS) — A system for blockchain currencies in which the rewards given out for the creation of new blocks is given proportional to people’s stake, or volume of currency. Explained in more detail below.
Proof of Work (PoW) — A system for blockchain currencies in which the rewards given out for the creation of new blocks is given proportional to the computational resources contributed to the creation process. Called “mining”. Explained in more detail below.
Public Key — Your wallet address. This is the key you will share with people in order to have ether sent to you or requested from you.
Serenity — The fourth of four major phases for Ethereum. The biggest component of this release is the move to a Proof of Stake system via the Casper algorithm.
Staking — In a Proof of Stake system, this generally means leaving your coins in your wallet to increase their stake in an attempt to net rewards from block creation
Stop Buy — An order which is triggered by the act of a traded commodity going above a price set by the trading party.
Stop Loss — An order which is triggered by the act of a traded commodity falling below a price set by the trading party.
Technical Analysis — financial analysis that uses patterns in market data to identify trends and make predictions.
Whales — Traders with massive amounts of the currency being traded. They are able to sell and buy in quantities large enough to manipulate the market price in the short term.
zkSNARKs — A method for allowing members of the Ethereum network to validate calculations without knowing what the original calculation was. Expected in the Metropolis update. Explained in more detail below.
What is Ethereum?
At a very high level, Ethereum is a network of computers that supports the execution of programs and transmission of data. The key difference between this system and how the internet works today is that while apps and web pages are hosted on a single server (or small cluster of servers), everything on the Ethereum network is distributed. Any machine in the network can process calculations to determine the result of a transaction or piece of code in an app, and all the machines involved eventually reach a consensus on what the correct result should be. In practice, this means that apps cannot “go down” because of some single point of failure. As long as there are enough machines contributing to the network, everything built on Ethereum will persist and the network will ensure the validity of the blockchain.
Where does cryptocurrency come into the picture? Ether (ETH) fuels the execution of these distributed apps (DApps). In order for a DApp to execute a task, or for you to send some message across the blockchain, there needs to be a small amount of ether spent, which is proportional to how large or computationally complex the task is. It can also be involved in the way an application works, such as a site that charges for a service, or a site where users transfer funds between each other for selling items, gambling, etc. A huge advantage of currency exchange via ether on the Ethereum network is that these transactions are extremely fast, taking no longer than 15 seconds (new block creation time) plus the time to reach consensus. At the time of writing this, the median wait time is 35 seconds. This time will decrease further in the next iterations of Ethereum.
Aside from being able to fuel applications, ether also functions as any other cryptocurrency does. It is used as an anonymous* ways to make purchases from an Ethereum wallet. If you’re familiar with how Bitcoin works, ether can be used the same way. Spend it directly at any online storefront that accepts it or sell it on an exchange for cash, another currency, or anything else available.
Getting an Ethereum Address:
There are multiple ways to get an ethereum address, but the easiest way by FAR is using https://www.myetherwallet.com/. MyEtherWallet is open source and can be downloaded for use off-line or on an air-gapped machine if you’re so inclined. It does nothing more than interface with the existing command line interface of ethereum ([geth]).
- Go to https://www.myetherwallet.com/
- On the Generate Wallet screen, create your password. Also known as a wallet SEED. I recommend using several words (at least eight) as your password.
- MAKE SURE YOU WRITE THIS DOWN AND KEEP IT SOMEWHERE SAFE
- It is not recommended that you keep this phrase/password on your computer.
- You should see this information
- The funny little blocks there are QR Codes for your public and private keys.
- Keystore file
- Encrypted information about your wallet. Can be used to unlock your wallet, SO LONG AS YOU HAVE YOUR PASSWORD!!
- Your address
- This is your public address. Ethereum can be sent to you and requested from you at this address.
- Unencrypted private key
- This can open your wallet WITH JUST THE PLAIN TEXT. Never share this with anyone. Do not store it on your computer. If you want to keep it, write it down and keep it in a safe place.
- Paper wallet
- This will contain all of your account information including your private key in a printer friendly form.
- Unencrypted JSON data
- Contains all your account information including your private key in plain text. This can be used to access your account. DO NOT SHARE THIS WITH ANYONE.
Purchasing Ethereum Through a Third Party:
How to Buy & Sell Bitcoins & Ethereum with your Credit Card / Bank Card
In this guide we are going to show you how to buy bitcoins easily using your credit or debit card at one of the top…
You’ve got your wallet and now you’re ready to get yourself some ethereum. This step is pretty simple, so I’ll do a quick high level for Coinbase.
Go to the Coinbase website and click the “sign up” button in the top right hand corner.
- Fill out all your information and verify your account.
- Coinbase will be asking for sensitive information regarding your identity. This is to comply with federal money laundering regulation.
- It is HIGHLY RECOMMENDED that you set up two-factor authentication with your cell phone in order to better secure your account.
- Coinbase will prompt you to add a new payment method before you can buy Bitcoin or Etheruem. Methods include bank accounts, as well as Credit/Debit cards.
- Buying from a bank account will incur a 4–5 day wait time, and a 1.49% fee.
- Credit and debit cards purchase instantly, but incur a slightly higher, 2.49% fee
- Once your coins have been purchased and are in your Coinbase wallet, it is recommended that you move them off of coinbase and into your own wallet. Preferably cold storage.
- To do this, simply click “Send/Request” on the side bar located on the left
Set the correct ethereum address in the “Recipient” box, along with the amount of ethereum you want to send and click “Send Funds”
Purchasing Ethereum Via an Exchange:
This gets a hair more complicated, but it’s worth knowing this stuff. I’ll be using Binance in my example, but this terminology will carry over to any other exchange.
Beginners Guide to Binance — How to Use
After the hype in the crypto money market, many investors actually have questions like what is Binance, how to use…
This is the order book. The order book shows you how much of the traded currency is being bought at a certain price.
So right now it looks like there’s 618 ethereum being PURCHASED for a price of $27.84, so ~$17,000 in ethereum. If you ever get confused about which side is which, just remember that you’re always going to want to sell YOUR ethereum to the person willing to buy it at the highest price.
On the other side of the buy orders, you have the sell orders. They’re exactly what they sound like. These numbers indicate how much ethereum people are willing to sell at a given price.
So like in the above example, someone is willing to sell 447 ethereum at ap rice of $28.15, so ~$12,500 is for sale at that price.
I would highly recommend also reading this. It gives a pretty good high level view of what a buy wall and a sell wall are.
THE PRICE CHART
This is the price chart. On the price chart, you can see what price ethereum and other cryptocurrencies are currently being traded for. The vertical bars are called candles, and they indicate at which price the item opened and closed during the interval. A red candle indicates an interval in which the cryptocurrency, in this case ethereum, opened at a high price and close at a low price. In other words, it lost value.
For example. If at 8:00 AM etheruem traded for $10.00, and at the end of a five minute interval, it was trading at $9.50, there would be a red candle to indicate this.
Conversely, a green candle indicates that the cryptocurrency opened at a lower price and closed at a higher price, gaining value.
THE ORDER BOOK
This is the order book. This chart gives a graphical representation of how much ethereum is purchasable up to a certain price. The total volume available at a given price is represented by filling in a section of the graph representing either a buy or a sell.
In this example, the buy side is green and the sell side is red. This is fairly standard on all exchanges, but could possibly be different.
This is the trade history. This is simply a representation of the most recent transactions on any exchange. Once again, green represents a buy and red represents a sell.
A Market Order is simply an order at a given price or total number of ethereum. This will give you the best price or the greatest number of cryptocurrency that you can get for a set amount of ethereum or a set number of dollars. These are more designed for immediate buys, and not to get you the best price possible. That is to say you would be better off setting a limit order.
For example. If you place a market buy for 100 ethereum, and the order book has 100 ethereum available at $10 each, you will buy 100 ethereum at $10 each and pay $1000.
On the other hand, if you place a market buy for 100 ethereum and there is only one ethereum available at $10 each, and 99 ethereum available at $100 each, you will buy one $10 ethereum and 99 $100 ethereum, for a total of $9,910.
If you were to place a market buy for a set dollar amount, then the exchange would simply purchase you as much ethereum you can afford at the lowest price possible.
So buying $100 in ethereum in our first example would net you 10 ethereum, but the same order would only net you 1.9 ethereum in the second example.
A market sell has the exact same principle, but obviously is the act of selling rather than buying.
For example, if someone was buying 100 ethereum for $10 each, and you set a market sell for 50 ethereum, you would sell 50 ethereum for $10 each, for a total of $500.
On the other hand, if there is only one ethereum being bought at $10, and 99 being bought for $1, the same market sell would sell one ethereum for $10 and the remaining 49 for $1, netting you $59.
A limit order is simply an order at a set price.
If you place a limit buy for 100 ethereum at $10 each, then you would buy 100 ethereum for $10 each SO LONG AS SOMEONE IS WILLING TO SELL IT TO YOU AT THAT PRICE.
If you place a limit sell for 100 ethereum at $10 each, then you would sell 100 ethereum for $10 each. Again, only so long as someone is willing to buy them at that price.
One small caveat is that if there exists an order that is the same or better than what you are currently setting, then the exchange will automatically execute it.
For example, if you placed the same market buy for 100 ethereum at $10 each, but someone was already selling 10 ethereum for $9 each, and someone else was selling 15 ethereum at $10 each, then you would BUY those 25 ethereum and set a limit buy for 75 ethereum at $10 each.
The same applies to a limit sell. If you set a limit sell for 100 ethereum at $10 each, but someone is already buying 10 ethereum fat $11 each, the market will automatically sell your ethereum to them at a price of $11 each.
BUY STOP/STOP LOSS
A stop order is simply an order which is triggered by market action.
A stop loss is a market order which is placed by you at a given price if and when the cryptocurrency trades at or below that price
For example. If I wanted to make sure I didn’t lose money on a margin trade overnight, I might set a stop loss at $10 each to sell 100 of my ether.
I might also place a buy stop in order to make sure I didn’t miss out on the rising price of a cryptocurrency.
For example, if I thought the price of a cryptocurrency might double overnight, I might set a buy stop at $10 in order to not miss out on possible profits. Nobody ever made any money buying at the top!
Note: GDAX No longer supports STOP orders for anything other than API trading.
In the following section, a few key principles of Ethereum will be discussed. It is not necessary to understand these concepts if one is simply interested in purchasing ethereum and holding on to it. This information will attempt to explain a few of the more ‘technical’ details of Ethereum at a high level.
Proof of Stake (PoS) vs Proof of Work (PoW)
Proof of Work is the system by which most cryptocurrencies, including Bitcoin, manage their blockchains. Through a process known as mining, individuals contribute processing power to determining what the next block in the blockchain should be. Whenever a new block is created, whoever was lucky enough to be the person that created that block is rewarded with some amount of currency. The difficulty of these calculations can be determined by the devs behind the currency to control the rate at which new coins are dispersed into the economy. A higher-level way to think about this is that processing power is what creates scarcity and is proportional to the odds of you getting the next reward. This has the unfortunate side-effect of giving a disproportionate amount of power, in regards to both reward and blockchain validation, to miners that control a large portion of the mining hashrate.
On the other hand, in a proof of stake system, rewards for creating new blocks on the chain is provided proportional to your “stake” in the economy as opposed to the work you can do. Your stake increases based on the amount of currency in your wallet and how long it’s been there. The longer you have coins in your wallet, and the more you have, the higher the odds are that you will receive the reward for the creation of the new block on the chain. As of March 2017, Ethereum is using a Proof of Work system. By the Serenity update the platform will be updated to use a Proof of Stake system. As we get closer to that release we will learn more details about how the PoS system will work in Ethereum’s implementation, known as Casper.
To explain the importance of zkSNARKs, let’s first quickly go over how the Ethereum network works. Whenever a new calculation is made on the network (a new transaction is recorded, some piece of code is executed as part of an app), some number of other nodes need to confirm that the calculation was done correctly before the result is recorded in the blockchain. In other words, everything needs to be double-checked enough to be universally accepted. As you might imagine, the easiest way to do this is to make the calculation visible to everyone on the network so they can each run the calculation. This is how Ethereum works now, and it has shortcomings, such as requiring all apps on the network to be open source. That’s where zkSNARKs comes in.
“Zero knowledge succinct non-interactive arguments of knowledge”. This allows us to manipulate and translate calculations that need to be double-checked so that nothing on the network needs to know exactly what the original calculation was, but can confirm whether a result is correct or not. This means that code deployed on Ethereum doesn’t have to be open-source, and the details of transactions can remain completely secret. zkSNARKs will be implemented in the Metropolis update.
Metropolis is the next major update to the Ethereum network, the third of four phases that the developers have planned for Ethereum. This update will bring with it modifications to the way that applications interact with the network, making it simpler for developers to write apps on the platform. zkSNARKs will also be implemented in this update, opening up the Ethereum network to developers that want to keep their apps’ source code a secret which is expected to attract a large amount of new development.
This is the fourth and final major planned update to Ethereum. This is defined by two massive changes: transition from a PoW to PoS system using the Casper algorithm, and sharding. Sharding will allow applications to be split into tiny pieces, or sharded, and distributed across the network. One calculation required to execute an app may happen on one machine (and then double-checked using zkSNARKs on several others), then the next calculation happens somewhere else, and so on. Not only does this improve performance by reducing the time it takes for apps to execute on the network, allowing network nodes to validate only shards of the blockchain means that new blocks can be added, and transactions confirmed, near instantly. This is the biggest update planned for Ethereum and has no release date yet determined.
Looking Forward / Closing Thoughts:
It is my personal belief that Ethereum has a very bright future ahead of it, but that is not to say that there are no risks involved. Ethereum is a young, innovative technology with many dedicated developers working tirelessly to push us further into the future. However, one must keep in mind that innovation doesn’t necessarily mean success. While I do not personally hold this belief, there is always the possibility of something going catastrophically wrong, and ethereum as we know it could be put to an abrupt end.
Please keep in mind that investing in Ethereum right now is investing in a speculative, volatile market. Things are going well now, but that isn’t to say that it will always be this way. Don’t invest money you cannot afford to lose, don’t try to time the market, and be sure to express all the risks involved with discussing ethereum with friends and family.
