I bought some BTC on Coinbase last night and had it sent to Poloniex. I know the BTC wallet address was accurate. Its still pending 11 hours later and doesn't show up in the Poloniex deposit/withdrawal history. Any clue on how long BTC transactions are taking?
Its on coinbase fault on which they dont still send those bitcoins which it wont really show up on the address on your poloniex. I do have recent transaction with coinbase transfer which i do make a withdrawal and for how many hours i do still see pending state which means they are still holding such transaction,it took for almost 12 hours or 15 hours but i didnt still bother since coinbase would really sent out those bitcoins and luckily the transaction went through and i do receive the bitcoin which i do request. Just have patience pal.
