Very good question. I'm always leary of anything unproven.. But I hope it's there .
Also something about Apple, and bout visa to getting interested in BTC . I'm retired and in my life I came to wait for the real hard facts .
Anyone can speculate ,but it's better to be sure !
If Tesla was lying about their 1.5 billion USD purchase, then how will you explain the surge of bitcoin prices right after Tesla announced their purchase? We have to take their word for it even if we are skeptic about it. Hopefully, the rumors about these companies getting interested in bitcoin is something that will come to fruition, I agree that it is better to be sure but this are just rumors after all, we just have to wait for their announcement, sometimes the real hard facts are not facts until they are confirmed.
Bitcoin's price is a proof that Tesla really pumped bitcoin's price in the market by buying a huge amount of it.
$1.5billion USD amount of bitcoin is really something else and it takes a big company for that to be able to come into reality.
Tesla can do anything because it is a big company that allocates its money to help our technology develop and investing in cryptocurrency is not impossible for them.
