I don't follow the stock market's movement in relation to Bitcoin's so I can't compare past performances, but wasn't there a point last month where the dow plunged along with Bitcoin? Here's an article that details it, though it focuses more on the stock market side:
http://fortune.com/2018/02/05/stock-dow-bitcoin-market-crash/That incident makes it seem to me that the stock market crashing would have little consequence for Bitcoin prices. Heck, it could even be surmised from that that a stock market crash would also mean a Bitcoin crash. Personally, I think it's far more likely that they just don't have anything to do with each other.
Either way, we don't know if the stock market is crashing for sure, and we certainly can't conclude that it will result into a Bitcoin pump.
