Bitcoin is easy to use and transfer to buy online. it's no fee and no tax and it's anomynous.
Payment online is very fast and safer than fiat.
Well yeah but I don't quite agree with you about fast and safer payment. Because the transaction confirmation time is still a bit problem, it's not true to say this. And also, I don't get what you mean by saying that it's safer than fiat, how safe is it or can we even compare bitcoin and fiat money this way?
In international transaction case, bitcoin is much faster than money. You know, if you send some amount of money to someone in other country through bank, imagine how much time you have to spend and I guess the fee is high imo. I think the reason why he think bitcoin is safer, because you dont need to carry fiat with you everywhere.
