I give good nominations.
Kraken number one always working never problems.
Poloniex old and helpful support.
Binance well... They should work with their down time problems.
So kraken should teach others how to build good exchangers!!
In the World we need more quaility and I hate when things dont work everything should run like clock work!
Im telling you if poloniex and kraken goes down the all cryptocurrency will go down!!
So until I see polo and kraken good we are all good
There have a lot of Exchangers on online platforms and every exchanger have some problems.I am using bittrex and binance and coinbase for trading. I recommended to anyone who wants to trade or find the best Exchangers.Binance and bittrex have a huge volume of asset and supply on the other hand its most secured and safe Exchanger and never stole your private information other.
