Having checked out the site and saw some popular coins there but in my own opinion, the price I had seen for ETH in the past is still close to what I am still seeing which means the margin is not really much which a trader might not cash into because the spread will not generate enough profit compared to other ALts which could fluctuate and I could make some money. In that regards, I will join those who are asking for more coin be listed that admin should look into it as well...

As I noticed the price for bitcoin is lower than on that site that I have used before. It's even good to me cause of I plant to buy some mBTC when the price for bitcoin get down under 900$ again.

Can bitsane be used for wallet purpose of POS coins? I mean if we keep PoS coin in bitsane, will they stake?

if you trade without fee, how exchanger can get profit, in operational use money
but same huobi and okcoin support margin trading, exchanger can get profit from lending fee, and lost client
without margin trading and not use fee , exchanger can't get income

No, i dont think it will work staking on bitsane or any other exchange for POS coins. Staking only works on the desktop wallets.
The algorithm for staking does not work on the exchanges.

yeah, that's right. if the exchanger has no fee, then there is no advantage possessed exchanger. Well, there should be a fee on every transaction that occurs in every exchanger, even famous exchanger also has a large fee.

if you want sugestion bitsane without fee is not good sugestion

I am against the no trade fee because it will lessen the sites source of revenue but thinking  about the possibility if having more users, then I think it will be covered by withdrawal processing fee.  And a well placed advertisement banner. 

Big users without trading fee is better than a few users with fee.
