with all the conveniences we get from bitcoin it's not wrong in my opinion we need Bitcoin,
Practical in terms of the current situation, but looking way to its characteristics, it isn't really practical to use bitcoin for daily transactions. Perhaps, for trading and investment, it is good because of its noticeable high volatility. What I hope for in the future is for the price to spike high and remain stable. Therefore it could be available for anyone to use to transact for product or services they want.
With regards to government regulation, the development of bitcoin from other country who already accepts it (for me,) will be the reason why other country should accept bitcoin as well. It is now the new revolution of currency for international payments and it opens up tons of opportunity as well especially when reducing payment rates for international transactions.
