I haven't had any problems using Huobi or withdrawing tokens. Although some coins are more expensive to withdraw than others. However, I think that US Citizens are not allowed to open accounts there.
AND their deposit and withdrawal feature for Steem is still closed. Only the Steem already held in accounts on the exchange are trading.
Ah, aha.. that may be why their price is high then - it is common for the price of tokens on exchanges to increase during periods of wallet maintenance or downtime. Thanks for the info -I'll probably take a look around in there anyway as its the only place i've seen that lets me directly exchange steem for usdt which can be useful at times. :)
