Because you a newb and don't know what you are talking about. Do you think if there are laws that are somehow going to make crime magically go away? How does asking customers for KYC stop fraud?
This article is biased and I don't even know how true this all is. But sure believe what you read online.
For some reason Paypal is better for business, because they keep it fair. You can ask for a refund if you got scammed. With crypto, you can't.
So, it can't be better than any form of traditional payment solution to be frank (unless what you are doing is against the terms of the particular payment processor).
Yes because paying 7% fee is awesome for your business right? Why would you want there to be refunded? So someone can do a chargeback on you?
