One thing I can offer is to try out our simulated crypto currency exchange. The good part about it as your trades are based on real market movements, you can do leverage trading and pretty much everything that you could do on the real exchange. Multiple portfolios also allow to test multiple trading strategies all at once. This way you can see how you could perform as a trader if you could take out emotion out of the picture, since you are trading with play dollars.

My personal favorite is Kraken. I know they had fare share of their issues, but I like them being quite transparent. Also tried Poloniex and Binance. I did not like Poloniex at all, and Binance is okay due to the fact that they have bunch of altcoin trading pairs.

This is exactly the reason why we have built https://niffler.co the cryptocurrency exchange simulator. People on our platform love to see how they perform without the fear factor of losing real money. This teach a very important lesson - never make trading decisions based on your own emotions.

The Coin Shark, it would be awesome if you guys could cover this on your media outlet https://niffler.co/bitcoin-graveyard/
