3. cryptocurrencies stop the Austrian economics fetishism and index the coin reward to the mining difficulty. That means getting rid of the fixed coin supply.
That would stabilize the price of the token a lot (since price going up would increase the mining appeal, thus expanding the money supply, driving the price down) and also make it much more usable as a mean of payment (the number of token in circulation would grow in parallel with the growth in users).
Obviously it's not gonna happen, because those people have spent a decade convincing themselves that deflation is good and fixed money supply is the righteous way to manage a currency.
