I don't know how to buy spacex. What I buy I want to 95% buy and hold, I haven't studied spacex at all... Much less hundreds of hours. And bitcoin I can actually own your keys your coins etc. Whereas Spacex shares trade through a brokerage. I know how much bitcoin will ever exist, I have no idea how much spacex will exist. I can buy lunch with bitcoin how do I do that with spacex or custody the shares myself
