I am very sure btc is going be the currency used worldwide in future after may be 10 years. This digital currency is really getting spread everywhere. Everyone here in this forum is experiencing btc's benefits. Really thank the one who innovated this currency, Signature campaigns and this forum.
Bitcoin will be the future for sure and that is because you also can see now that the price is going to rise in the future and that is nice because we all waited a long time to get profit.
So the time will be soon to sell it with a lot of profit and that is perfect for us.
