You do realize that TSLA is worth at least 3x the latest estimated valuation of SpaceX right?
Also, it wouldn't be risking SpaceX at all, all they are being asked to do is convert some of their cash into bitcoin. The risk of doing so is minimal but the reward is unbounded. Especially considering how investors tend to add premium to the stocks of companies that hold BTC.
Well if you think buying bitcoin has minimal risk we can end the discussion here. Too much invested in, as said.
All goes up and down, there is no real reason for it to go higher, other than hype. There is new and better technology. Doesn't make sense to continue to support bitcoin, imho.
Has already served it's purpose: to introduce cryptocurrency to the world. That's it.
