Yes. The Bitcoin Gold crediting and market opening will be done within 24 hours. Its a market for BTG futures (not actual BTG yet), though, but that's exactly what people like me needed - to dump it as soon as possible
HitBTC is indeed in a very good shape now. Few months ago it was Poloniex who was on top I think, but then they start having problems with slow support respond and people basically get scared so they move on to another one. This kind of competition only means good for users, forcing those exchanges to keep innovating and improving their quality.
Yes, did it very quickly. Lately HitBTC are my favorite exchange. They are improving daily and their support now is one of the fastest around.
I think they made a good decision to announced early that they are going to support Bitcoin Gold. I remember the price suddenly above $6000 when they told their followers on their official twitter account. And yeah its an old thread but suddenly becoming relevant as of today because its looks like they are really giving the top three a run for their money in theirs of trading and volume activity. I would be honest to tell you that I have tokens deposit in there and withdrawals are very quick as well. Initially I have doubts about this trading platform, however as time passes by they already gained my trust and the community as well. In no time, they will be another force to reckoned with.
