The BTC mechanism for attempting price stability on the other hand does the opposite: the supply is designed to grow very steadily, but with no reason whatsoever to believe a stable and sustainable demand for that particular cryptocurrency exists in future.
[1]Hyperinflations occur when the supply of money grows steadily without even bigger growth in future demand obligations, which in practice invariably happens because the government has resorted to printing it to discharge debts and release people from future tax obligations. This actually looks more like a Bitcoin economy (albeit with more potential for the money supply to grow really, really quickly) in that what the government is doing is decoupling supply from demand.
The risk of Wiemar-like circumstances striking again in the West are basically zero, unless a Wiemar-like perfect storm of defeat and ignorance strikes again; and even then, hyperinflation never lasts long (no one can live under it for long). One woman weathered the Wiemar hyperinflation by selling one link of a gold Rosary chain a day to buy food; a quite modest amount of precious metal is enough to outlast this sort of disaster.
