1.In future buying bitcoin is more easier than past condition ad people can complete so many task very easily.

3.international client are more visible if this currency will use globally.
4.in future if government use the protocol then cyrpto-currency will protected and people feel safe for using this currency.
Logically, you have those four good points and that is really be the future of bitcoin even though at number 4 many will never agree but it is really needed when things get worst in the scamming issues that might ruined the cryptocurrency and can affect the bitcoin community. It is the reality we should accept that we cant hold a secured and safe investment out of it without the help of the authorities. Those that mostly oppose on this are the one doing or benefitting from the illegal things and afraid of jail time.
