I do not know about the Kaiser prophecy but something that is present in the minds of 8 billion people as the dollar can hardly die.
Inflation, yes, there will be inflation and the dollar will be wounded, but BTC is not and cannot be a currency. The American economy will remain dependent on a sick dollar just as the Argentines have kept using pesos rather than gold and would have kept using only pesos if it had not been for the US dollar. Except the Americans won't have that exit strategy that the Argentines had, because BTC cannot be to the dollar what the dollar was to the Argentine peso.
