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
Bitcoin cannot be a currency but a good channel for exchange. It has a lot of features yet to be polished like scability issue, volatile in nature, unpredictable. So bitcoin cannot still be money because not people can understand it and its usage especially those who are not technology experts.
