"SUPPOSED", according to which authority? Let's be real, the vast majority of the development into crypto currencies is due to the speculative qualities that comes from having a limited supply of coins. Stable currencies works fine only in cases where there's significant power structures/momentum behind them. If Bitcoin didn't increase in value with increased usage, barely nobody would use it (since nobody/nothing would support it). Bitcoin had neither when it launched.
