Elon musk has an entrepreneurial mindset and that's why he could confidently invest in all these projects ignoring the fear of unknown. I like his courage really, and no matter how you want to put it, he can never be broke even if all these companies fail.
He is one that has always believed in cryptocurrency and has some BTC, Eth and Doge coins in a wallet tucked away somewhere.
In 2021 when Tesla purchased some BTC, it could be likened to a whale move and it effected a price hike to about 25% which recorded an ATH of $48,000 as at then. Although, it was because it announced it was accepting BTC payment for new purchase of Tesla vehicles with as low as $100 deposit.
When Tesla stopped accepting payments with BTC, the interest rate however dropped to 10%, this just goes to show you that despite the attention, a whale is a whale, and Elon and his Tesla and SpaceX are big whales in the cryptocurrencies ocean.
You have an interesting position in relation to Ilona. It may be true about entrepreneurship, but this world can be incredibly harsh. Force majeure circumstances can happen to this person at any time. What to do then? Who will run all these companies? After all, not all of his relatives have a predisposition to this. What will happen to all this finance? It seems to me that not everything is as clear as you write.
Yes, Musk has crypto in his accounts, but he is not going to keep it forever. The right moment will come for him and he will throw everything off. The market will, of course, react to such an event, but then everything will return to its previous course. This has happened more than once. Therefore, there is no point in believing in him like that. Everything has some measure.
