Crypto Currency can be fun but only when you are not losing money! All crypto currencies are like gambling chips and the exchanges they are often traded to are like the casinos.
This is because a lot of people are trading real money for bitcoin and then bitcoin for currencies like Compound Coin.
We do not recommend you buy any Crypto Currency with real money. However, you can learn to utilise fucets to gain free coins, MINE when cost effective or stake high interest coins (like Compound Coin). Swap these coins gained with other currencies to further gain more Compound Coins.
