I often use hotbit, this is an exchange according to my review as well. In general, from the interface to the volume of transactions is quite good, but I do not use HTB currency pair often. I think if Hotbit keep doing well but now, it is likely that Hotbit will rise to the top.
I use Hotbit sometimes too and I can say that it has a good interface and fair withdrawal fees, but I don't know if their token can be successful though, they have a lot of competition from other exchanges that people are using all the time and it's hard for them to change to another, Hotbit is a typical exchange that you go to just to sell some specific tokens that aren't available in your perfered exchange, it is doing well now but I don't see it make a step further and get higher in ranks of bet exchanges.
