As green tricky said use coinbase pro although if it’s for a one off coinbase fees aren’t the worst.
For selling I either use that or Binance although been reading a lot recently that Binance have been banning accounts for no reason, which is slightly worrying
What kinda fees do Coinbase hit you with? I should really look into it. Also is it a total ballache to try and withdraw from your Coinbase wallet?
Again, I should probably watch a video or something
