I really dought that any exchanger can (or will) give you the dividents if you keep your tokens there.
They probably don't want to do extra work/deal with it. if anyone had kept CSNO on exchanges their dividends will be taken up by exchanges. tokens that distribute dividends are best kept in private ETH wallet/address.
Yes exchanges never credit such transactions to their users. They take it and add to their profit.
And which exchanges have CSNO listed anyway. There's only HitBTC afaik. And according to the Monero community, it's shady as f*ck. Tho I don't have any problems with them so far...
I'm avoiding doing any trades at hitbtc, their deposit fee scares me off. suppose you want to sell your CSNO, the deposit fee currently is 168 CSNO/ 5 mBTC. would you pay that much of deposit fee? i won't. ED is a better option, but it lacks liquidity.
Yes HitBTC is known by high fees. But many exchanges have them and fro most coins. Usually when people complain about high withdrawal fees, it looks like it is limited to that particular coin. But is not. As I remember from one list average of Binance fees was over $10.
