This sitution probably is another proof which indicates that Bitcoin is correlated with S&P 500 and some other stock markets more than any time before. However, in a free and ideal market, which obviously is not applicable for bitcoin market currently, the price follows a logical trend, which can be predicted to some extent.
I guess people are so desperately try to find somewhere to invest their money, making some ephemeral mirages!
Bitcoin still needs to find its own way and prestige instead of imitating others. I hope to see that independence in Bitcoin someday.
My advice is just to be carefull!
Still I believe there would be a downward trend in near future.
