yes afcourse i believe in bitcoin 100%... I just started bitcoins few while ago and i have earned well so far and exchanged few to my fiat currency and invest some for gambling and making more profit. i would defnetly say bitcoin is something unique that is going on evolving and im sure it will find a better place to fit in future:)
Yes, there is no doubt that in the coming future bitcoin will be the first used currency and everyone will refer it for their international transactions, and after that people will support it more and will make it a global currency.
Yeah and bitcon will be the best digital currency for sure, we will see many new users investing their money into it and start using it as a currency and a payment system.
