Well I got bad experiences. Sent 55k siacoin from poloniex to unlock hosting features. I checked the transaction in the blockchain and found that the input and output was complete. I mean sia recieved the coin and sent to my wallet. The problem is I HAVE NO BALANCE in my wallet . So I wrote on their forum they answered that the poloniex can have trouble with withdrawals.... but the transfer happened... The address was correct. What can be the problem?
