Imagine you’re watching the 15-minute chart of Bitcoin on your favorite exchange. All the signals in your trading strategy are indicating the price of Bitcoin is about to fall, so you decide to sell off your position in Bitcoin.

But when you look at the cost of your trade, you see that you sold your BTC at a significantly lower price than what you’d seen on the exchange. …


The many possibilities of crypto aren’t worth much if your funds aren’t secure — and nowhere is that truer than in the case of Ethereum.

On November 7th of last year, just as many were learning about Ethereum and creating ether wallets for the first time, a user discovered a bug in the widely popular Parity wallet that indefinitely froze the funds in all of their multi-sig wallets. An error in Parity’s smart contracts left its multi-sig users — those who were trying to get the most security available — with no way to access their own funds.

Ethereum aims to be a global, decentralized supercomputer. But just how secure is it?

On April 30, 2016, the DAO — an automated, decentralized venture capital fund — was launched on Ethereum. Less than two months later, it was hacked, and over $60 million worth of ether vanished in an instant.

The potential of new blockchain technology like Ethereum doesn’t count for much if it comes at the expense of security. Incidents like the DAO invite the question: Just how secure is the new, decentralized supercomputer that is Ethereum?

The short answer is this: Ethereum itself is more secure than you might think, but using a decentralized app or exchange that hasn’t be…


If you want to get past a first-round interview for a finance job, you need to be ready to answer this question: “Is arbitrage possible?”

Why is this question so common? The standard economic theories taught in schools start out with the assumption that markets are efficient — and, in an efficient market, arbitrage opportunities don’t arise.

But the real world isn’t quite like textbook economics: markets aren’t efficient, which is why institutional investors and savvy traders are able to use strategies like arbitrage to make outsized profits.

One look at the Bitcoin market will tell you that arbitrage…


Institutional investors and high-net-worth individuals (HNI) typically use over-the-counter (OTC) trading when they want to buy or sell a large amount of cryptocurrency.

That’s because while 99% of people who want to buy or sell cryptocurrency can do it directly on an exchange, placing an extremely large order on an exchange can be a costly enterprise.

Say that you’re an institutional investor trying to buy $1 million worth of Bitcoin, or that you’re a cryptocurrency start-up that’s trying to sell $1 million worth of Bitcoin raised through ICO. …


If you think that the Bitcoin network is at the mercy of its miners, you’re wrong.

If you think that it’s at the mercy of its developers, or its users, you’re wrong, too.

These sorts of polemic stances that accuse one group of having total authority over Bitcoin are all too common in casual conversations and established news sources alike. …


Today, we’re thrilled to announce that SFOX has closed a $22.7 million round of Series A funding, led by Arjun Sethi from Tribe Capital and Social Capital. We believe that a company should only fundraise if it has a clear vision for how those funds will translate into compounding value for its customers, so we want to give you a glimpse of how we plan to do exactly that.

We founded SFOX in 2014 as a way to solve the problems that were preventing institutional investors and HNWIs from investing in Bitcoin. We saw an asset class that had…


To many, Bitcoin is synonymous with risk. That’s because the price of Bitcoin has been extremely volatile over the years:


If you’re buying or selling a 100 or more BTC at once, you probably don’t want it at the mercy of the market: you want a trading method that protects you from shifting market position or the slippage that happens when you show your hand before the deal is done. For some people, that method is trading with an over-the-counter (OTC) broker who directly finds a counterparty for your desired trade.

The idea behind OTC trading is that these brokers can provide a quoted price for large transactions and shield high-value traders from adversely impacting their own price point…


On January 9 of this year, the price of Bitcoin in South Korea was 43% higher than it was in the U.S.

If you’d had a way of buying $100k USD of BTC on SFOX and selling it on Bithumb without any fees, foreign currency exchange rates, or time delays, you could have pocketed $43k. That’s the financial tactic of arbitrage: the practice of buying an asset and immediately selling it at a higher price for a very low-risk profit.

But of course, it’s not that easy to buy BTC on one exchange and then transfer and sell it…
