Some banks and corporations said theyre halting purchases of Bitcoin and other cryptocurrencies on their credit cards. Banning it because they dont want the credit risk associated with the transactions. Some says that allowing purchases of cryptocurrencies can create big headaches for lenders, which can be left on the hook if a borrower bets wrong and cant repay.
it is difficult to ban cryptocurrencies everywhere, maybe they are banned by any state, but States can not manage cryptocurrency and it is impossible to stop the cryptocurrency system itself, it is necessary then to take away from people the Internet and electricity in General!
