Actually, Bitcoin may be available to be used for any kind of transaction. However, the problem is it will be limited in the countries and also other regulations. Sometimes, a country doesn't legalize Bitcoin or cryptocurrencies as payment transactions, like in my country. So, it will be only fit certain countries only maybe
Of course bitcoin can be used for payment method, if the companies accept bitcoin.
I think It is good news if we can pay real estate rents with bitcoin.
I also read Tesla accepted the bitcoin for their payment transaction.
I hope It's not just rumours, because bitcoin is the future currency.
