not sure if this is old news or not but I haven’t seen too many talking about this method so here it is. First buy the BTC on Coinbase and next What you do is Sign Up on GDAX which is the same company as Coinbase. After ID verification your Coinbase will be linked to your GDAX account and you can instantly transfer BTC from Coinbase to GDAX for free. Now that the BTC is in your GDAX. You then move the BTC from GDAX to whatever wallet you do you “Other” shopping with and voila , no more $30 Coinbase fees.
