I also feel the need to expand on the anonymity part that I stated, in case anyone else stumbles upon this post and the comments. When I say anonymity I really mean pseudo-anonymous because you don't have to create an account or give up phone numbers or email addresses (with Shapeshift) which is a big difference when compared to exchanges that require verification. But technically when the transaction takes place information about it is permanently stored on the blockchain that could be traced back to you, such as your wallet address. There are projects being worked on that are trying to create a fully anonymous digital wallet but obviously that has a whole different set of concerns which I'm not looking to get into in this post lol
