The future of crypto currencies depends on the actual users.
In a way, it depends on bitcoin principles mostly.
Its perfect store of value, independent, easy to transfer etc.
Its better "gold" than actual money

Future is bright

thats for sure.
Big money = an appreciation of price of bitcoin right? Well in order for its price to increase it must have an increase in demand. By the time all the BTC has been mined all 21,000,000 million of them you will have now a finite supply of BTC, its up to the demand of the consumers . Which leads us what does consumers need to demand btc?
