I've seen them pop up all around me, in small convenience stores and even restaurants. I was wondering if it's a good option to buy a gift for someone else, or are the fees too high and it's not worth it? Also I'm not sure how it works but figuring they give you a private key, and how safe is that?
Long as they're not the type that asks for ID. Yes. It's the only bitcoin I buy because KYC is very bad to go through to buy bitcoin.
Don't ever give your ID.
