I'm a kind of person that likes to try every exchange lol, so I have created an account with Coinbase, Binance, Bitfinex, Bittrex and Kraken. I also created an account on Cryptopia but I never made used of the exchange, created an account cause I saw someone mention that they are good, so I decided to create an account there which I never used till now, maybe one day I would try them out. Coinbase was what I started with but along the way I stopped making use of their website and switched to Binance, and it has been my number one till now and they also have a mobile app as well. I hardly use Bitfinex, Bittrex and Kraken. I am not a full time trader, I only trade when I have the time, but I'm always on my phone doing research and whenever I think it's the right time to place a winning trade, I never miss it.
