i would love it to have future, but there are some problems with this.. BTC has a great role of a pioneer of digital currencies. Will it survive a competition though?
1. it is very difficult to evolve. It has to go through hardforks which is a pain
2. it is based on an early version of blockchain which lacks features of new ones
3. BTC volatility is a problem for business use. Ever tried to indicate price in BTC? you'll wake up tomorrow and see that you are now collecting 1/2 of revenue per unit (in your stable fiat currency) while your costs are still where they used to be.
4. permanent growth that is built into a model cold actually be a problem. For now it looks like potential profit from growth is not compensated by higher risk. That presents an arbitrage opportunity, that has to be wiped out in an open market. We'll see how this will work out.
