Yes, I’m a newbie to all of this. I have recently made 2 small Bitcoin purchases. $100 ea. One through Bitcoin com MoonPay. The other was on Coinbase. The first purchase on Bitcoin com/Moonpay cost me about 15% ($100 purchase). Coinbase was only about 3%. However, ever since my first purchase on Coinbase they have been unable to verify my identity!! Go figure. I want to buy more Bitcoin but looking for a better place to do that. Any suggestions? I will want to use ACH payment. I have been successful in transferring my coins to my Trezor wallet. Worked great.
