Decided to move all my funds from hitbtc to other exchange.
Firstly, why are you doing this? You should keep your coins in your wallet once you have completed trades and not store them on exchanges. You are not in control of your coins if you store them on any third party site and you are at risk of hacking and the site going down.
Thinking about DEXes. Could you recommend one?
Surely I can do that but consider reading what I wrote above.
Used EtherDelta and ForkDelta for now. IDAX turned scam so you can see how shady these marketplaces can be. ED and FD are safer though but no guarantees. Binance DEX is the recent one by Binanace, have not used it but I have heard it is good.
