Haha, nice try. Market cap of NYSE is over 20 TRILLION!!! LOL market cap of Alibaba is 231 Billion, Bitcoin is 5.5 Billion. Gee, I wonder which is more likely to be effected, BTC or NYSE???
Actually the evidence, the timing and correlation that is, do seem to suggest that indeed the BABA IPO had a direct effect on BTC price. Asian hot money sold bitcoin to play the IPO.
If this were true, then the IPO would have had a much bigger effect on the stock market, and it had no effect on the stock market.
