Bitfinex have now perfected there support system. They are present all over the social media with people who really look into your problems if you face any. I have till now in my 7 months have not found any bugs or problems. They have these wonderful ideas such as Digital Assets FIX Gateway which will allow crypto coins to be traded on stock markets. They offer margin trading with good percentage. I love the design and details of trading charts. You can easily liquidate your assets within seconds as there is huge market dept with millions of traders. They are up to date about there coins too, they keep on adding new coins which enables a lot of trading. I hope they stay the same. Recommend to everyone.
