Another question is, Is there a limit in withdrawal in this website?
I need to use this website because the token that I get from my bounty is listed on this trading site so you don't need to promote any other trading site. Thanks in advance.
did you check etherdelta and hitbtc? or did you check in the coinmarketcap.com? because I think before you decide to sell your coins, you need to check on which exchanges the coin is listed so you can send it directly to that exchange. don't I recommend you to not give your private key to access their website and I think there is an exchange that will list the coin and maybe you need to wait for a while.
