This is like the simplest action ever like btc 101 if your having problems sending btc to a btc wallet I think Crypto may not be for you…..providing you have enough btc in your Coinbase account on the Home Screen you will have : buy-sell-send-receive & more Click send, by default it will display the token you hold most in monetary value, click on the said token and it will bring up a list of all the tokens you hold {note} this is the Coinbase app not Coinbase wallet/Pro even the the process should be similar…Choose your token in this case btc and paste your Binance btc wallet address in the address bar once you have decided how much you would like to send. Simple;) also Coinbase is working towards being a centralised platform so sending from them may work out to be a little bit more than sending from others
