If China cracks down on miners, miners in other countries will just pick up mining....mining slack will be picked up by other miners and BTC will probably become more decentralized.

I'm not sure why this would cause such a crash ????????. I'm not one of those people put out posts urging everyone to hold during crashes or to buy the dip. There is such thing as negative news and times you should sell. I'm just saying this one doesn't really make sense.
