How to earn money from cryptocurrency

I would say it has many various ways to earn money from cryptocurrency, but I will separated into 4 main categories to make it easy to understand.

  1. Mining
  2. Trading
  3. ICO
  4. Others


Cryptocurrency is created based on the blockchain technology and cryptography, the completed payment transaction will occur when a transaction is already verified and put it into the proper block. So, who has taken this responsibility? the answer is “miner” and miner will rewarded when discover a new block.

P.S. maybe I could write about it more.


Cryptocurrency Trading is the Forex (Foreign Exchange) of cryptocurrencies, this means we take an advantage of opportunities in markets by trading one currency to other currency.

In general, cryptocurrencies are divided into 2 types; bitcoin and altcoin (alternate coin).

P.S. I will go detail in next EP.


Initial coin offering (ICO) is a crowdfunding via cryptocurrency, it’s mean startup or entrepreneur initiates and sells the “cryptocurrency token” for Venture Capital (VC). Investors who invest in tokens means they have a symbol of ownership for that project which can valuable if the project is successful. In contrast to IPO, investors gain shares in the ownership of the company.


Others mean everything that is not Mining, Trading, and ICO. LOL

For example, bitcoin faucets, mobile games, read books, watching short videos, play dice, and etc.
