If given the chance, I believe I'd diversify the money. Depending on my intentions (e.g. more interest in high outcome vs more interest in supporting technology) I'd go for a middle way. Today I'd buy GOOG and TSLA. If possible at the time I'd also invest in SpaceX because I really like their efforts. TSLA is more of a I-believe-in-this-tech thing while GOOG ist both the believe in their tech (especially since Alphabet owns SpaceX in part) and the desire to earn something out of the investment. Depending on my own financial needs I would go an split exactly in half or not.
