my view that the future of bitcoin lies in whether real-world merchants start accepting bitcoin as a legitimate method or means of payment. We've seen some merchants who accept btc, but desperately need more support if we want to see bitcoin to be the main currency that almost anyone can use.
You're right buddy and this is why it good to see some merchant in Japan, Germany, Korea etc accepting bitcoin as payment. However, I also believe the futures of bitcoin also lie on every bitcoin user by investing into Graft Network ICO because the main features of the project is to mainstream crypto currency through the merchant use, common human and consumer.
