Step 1: purchase $1.5Bn in Bitcoin

Step 2: make an announcement that will likely result in a rising valuation (it briefly went up by ~20% just because Musk added #bitcoin to his bio on Twitter...)

Step 3: sell 10% of your bitcoin at a profit of >$272M in Q1

Step 4: wait for the market to go up again, then proceed with Step 3

It's less risky to invest in a highly volatile, unregulated market if you have the means to somewhat steer the market just by making an announcement or have your company's figurehead add a hashtag on Twitter...
