Overall Coinbase is pretty good. Sometimes my transfers are not instant, but other times they are faster than expected. A few days ago, I had to fund my trading account with bitcoin. I used my Coinbase wallet. Well, I did not read until after that they said not to use Coinbase because it usually takes a while if you use Coinbase, but it was there within minutes! Customer Support is not that great, I have had emails with no reply at times. Overall, Coinbase is okay as it is safe, and insures, and well known.
