I just finally did my 1st transfer to Coinbase, in ETH. It was a few hours after a payout, I had a little over 0.014. I did the default full amount and it was a success the first try! I had read many people had troubles but, not me. Luck of the draw I guess. Was a surprise really. I took about 10 minutes and it now shows in Coinbase.
Just FYI, I did some looking around and it seems that around 5-7 pm PST (1-3 am UTC) is the best time for the gas fees being lower, mine was about 0.001811 when I transferred. I'm done with this mining for the foreseeable future. Just to slow on my single GPU with a lot of system use and electricity. I don't want to beat my rig up anymore except for gaming which I delayed for mining. Good luck everyone else...out!
