Bittrex or poloniex which exchange is best

Hii Guys this info is about who wana Do cryptotrading but don't know which exchange is best, They're both very good, and I use both of them. If you're trading in very small amounts, Poloniex allows you to buy or sell with a balance as low as 0.0001 BTC. Poloniex also allows you to margin trade which is probably more advanced trading than you want to do now but you can also make money by lending to the margin traders at interest. I personally prefer Poloniex' platform. However, the two platforms carry different coins, so which one you use will eventually come down to which one supports your coin, u also can try Bittrex bcs u will find new coin in Bittrex and made good profit.
