I am trying to purchase Bitcoin and I have a couple of questions to ensure that I am doing this the correct way. Thanks in advance for any helpful feedback. 1) Is it safe to use Coinmama to purchase bitcoin? 2) is it safe to use coinbase to purchase bitcoin? 3) Coinmama is asking to verify my identity so they want me to upload a drivers license and enter in additional information to verify my identity, is this normal? 4) what is or is this the simplest way to buy and then pay particular vendor with Bitcoin? Again I would appreciate any help with this matter. I just don't want to risk losing personal information and money using a phony Bitcoin exchange system.
