I have been using bittrex. I believe it is the most secure one in the market. However did bot list holochain. So I searched an alternative for holochain (hot) trading. Then I found out abcc is a good platform for "hot" trading. It was good. But only for hot/eth trading. when binance listed holochain I created an account in binance and then started to use binance .
