for my opinion about bitcoin, just me bitcoin is king of all crypto coin nothing else is similar and it is just alone. sometimes there are people who do not believe in bitcoin and there's also a country where bitcoin is not acceptable in their area, but for me there is no doubt this is one of the best digital currency in the world so it's a bicoin legit for everyone and in our future.
On my opinion bitcoin is a generalized type of currency that every nationality in the world may have. It is a private and secured way of storing an amount of money in a simple system of crypto currency. Therefore it must be legalized but limited to those who understands the use of it evidently.
