it does not matter and will have no effect. crypto users can do other ways to buy, they can still buy with debit card and bank transfer.
this is not something we should be afraid of.
Didn't you even realize all of the money went through wire and credit card payments? Both give a significant contribution to the crypto. But people can still buy crypto in another way, and it seems to be okay.
But it will give impact to the crypto. Those ppl are using them all to buy crypto through credit card must find another way.
