You should not think of bitcoin as a payment network, and do not expect its tech innovate rapidly. It is digital gold. Its most important property is to be secure and battle tested. I think bitcoin will be even bigger than it is now. If you zoom out into hundreds of years timeline, it has a historical significance: to store value in an extremely secure and relatively convenient way without trusting a third party. That is big. Probably will be bigger than 172 billion dollars market cap. It is competing with gold, which is something like $7 trillion. If you are interested in the future of payment, than you should invest into sometinhg like Dash instead, which is specifically designed and marketed for payment. Its price is rising rapidly, but it has not blown up as much as bitcoin yet. I hold an almost equal amount (in dollar value) in Dash as in Bitcoin.
