I joined Gemini last November after using CoinBase for several years. Getting the first wire transfer straight was a pain but since then the ACH transfers have all been flawless. The trading system is fine although it would be great if they added LTC to the mix. This is my 'go to' exchange for all of my fiat, BTC and ETH trading. Add in Bittrex for the other alts and you can be all set for secure crypto trading.
