bitcoin cannot replace currency in the world because price is not stable.
currency should be more stable.
you may reply me. currency is not stable also but you should think
USD currency price is up and down 1-2% in 1 month.
bitcoin price is up and down 20% in 1 month.
what will people think if they just change USD to bitcoin then their money down 10% in 10 minutes?
bitcoin can become stock but cannot become currency
it is true that this bitcoin can not replace the currency, because I think the bitcoin is an asset, trade, just a place. If this is made as a real currency this will make everyone go bankrupt.
