Ethereum Classic is a fork of Ethereum, this is a currency with many characteristics equal to ethereum, it is also one of the autonomous currencies on the market.
What I like the most about this project is that it has grown in the digital world, with this currency you can trade and obtain very easy profits, in addition to that this is well known in the digital world, it has many pairs available to trade with it, security ETC is very good although it depends on each user.
This cryptocurrency is de-centralized and belongs to the blockchain, which gives a lot of confidence to each of the users.
