The Tuesday plunge proved macros and cryptos are intimately connected. The Thursday plunge may have been the first sign of uncoupling.
Global GDP dropping would likely bring crypto down, but we haven't seen that one since pre-09 so its impossible to know. I would bet that a drop in the one would produce a dive in the other, but after this week, it may be different this time.
Clearly though, up until Thursday, when the dow dipped, crypto fell.
