Hillary has made it known she does not think too highly of bitcoin, fortunately the U.S is not controlling the price of btc.
If China disliked btc for whatever reason, then there will be a real cause for alarm.
OP is not referring on bitcoin economy, he talks about global economy. And we don't need to worry about Hilary or Chinese, bitcoin economy is just fine and growing.
But global economy had crashes in past, people should read about great depression and people need to know how easy that can happen again. OP is right when he talk about upcoming economy crisis in the world, that will happen and that will be the good for bitcoins, cause people will look for alternatives when fiat start to go down.
