I am, admittedly, new to Bitcoin but this question never leaves me. If bitcoin is not a bubble, if bitcoin somehow makes itself the international standard currency, what happens to the people who never bought bitcoin? Will they be provided a timeframe in which they will have to exchange their money from traditional currency to the cryptocurrency before traditional currency is phased out and deemed worthless or will there be another method of transition?
Bitcoin will never become an international currency but will be an alternative currency which belongs in the cryptocurrency. The paper currency in every country will remain as medium for payment. The bitcoin is the secondary option of payment once the business establishment will accept cryptocurrency.
