Coinbase fees are one of the worst. You can transfer from Coinbase to GDAX for free, and then from GDAX elsewhere also for free.
Thanks, this is interesting. I didn't know.
I have one question, anyway: let's assume a shopkeeper in Tokyo is selling me $20 worth of pizza. How can I be sure he'll get $20 worth of Bitcoin in his wallet?
If it depends on which wallet/system you are using, then it's a bit risky at the moment to keep accepting Bitcoin in the "real" economy.
I understand I can control my own transactions (the money I send to myself) using GDAX, and it's already a good thing, but when two different people are involved then it's too umpredictable. Should the shopkeeper ask "where are you sending money from?".
Sorry for the silly questions. Probably I really got in in the worst moment regarding the fees.
