I don't think this plot is very convincing. I will grant there's a feasible path that would imply causation, and Ferrari imports have increased just as BTC, SP500, and NASDAQ have. But aside from the macro-trend, the oscillations in the Ferrari import lines really don't seem to correlate with those investments. In fact, if you ran a linear regression on the numbers I bet you would find a _weak_ dependence. I can give you other things that correlate with BTC's move just about as much as Ferrari's do, just by manually looking for examples. For example, google search trends for 'electric vehicle'[1] and 'seed oil'[2] are both pretty close.
