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?
I just sent some today and was fast, 1st 2 confirms came within minutes. If its not in the blockchain thats coinbase issue not BTC.
