I dont know about topbtc. They have 36 markets yet they have that large daily volume. Do they wash trade? Are they useless exchange like fcoin? I have read negative comments about topbtc. I hope those comments are wrong. And topbtc will do great job for blue. Large volume will attract fresh investors and people will like the potential
Im sure topbtc will be good, I personally never have used it, but it seems to have nice volume
