I think no because bitcoin is used for online transaction and the price of bitcoin is not stable, but if bitcoin become stable maybe it might be possible that bitcoin will become currency, but for now, there's no chance that bitcoin will be used as currency.
The other reason every country have their own currency so where do you think the country of bitcoin?
Bitcoin is decentralized and we couldn't just credit it to China or other countries as their currency.
I think it can be accepted that btc today doesn't take the function as currency fully like fiat money.It can be ysed only for electronic and online transaction for short term.purpose. It is because of unstable price But this opportunity might be realized in the future after global regulation created and btc adoption formally.
