Apparently, if you are in space or some other zerogravity condition then you'll lose A LOT of body mass, but I wonder how much of that is attributable to malnutrition.
Remember, there's not a lot of things to eat in space, so you're pretty much stuck with non-perishable goods for your entire stay.
Since he wants to colonize on Mars he should be trying to make a machine so to exchange the atmosphere into oxygen.
You know a'la Total Recall.

As for the astronauts. Under the Biden administration SpaceX offered to get them 8 months ago but they refused due to political reasons. So the democrats rather have these people they put up there starve from malnutrition than put aside their difference and allow Elon and his company to rescue them?
They deemed them not being stranded. Well then what would you call it when you are trapped without a way to get back?
That does sound like being stranded to me.

Elon is playing with some things, even if not 100%. At the moment he aybe sad because the Cybertruck is not selling so well, the advertising for the car is well. Or if one of his spaceX rockets explodes, then he will definitely sad. But he is a gamer and i guess with so much money he will see some of it as play money. There are almost no limits for him, so why not play with bitcoin too. He has done the same with dogecoin in the past. I hope that one day he will manage to create a colony on another planet. Or maybe one of his children will do it.
When it comes to the crypto space he's already done that on dogecoin and memecoin in previous years but ultimately creating a hype for bitcoin is obviously going to be a 50/50 situation for him even less so.
Even if there is a buzz in the end that he did only for profit and the development for bitcoin was only for the short term not the same as the hype he created with the previous memecoin.
For sure in this case I doubt he really likes this kind of path by being in crypto other than for his own benefit by utilizing his popularity and large following in the end.
At the end of the day he's just playing around with things and I'm pretty much in agreement with this.
Tesla did have bitcoin on their balance sheet and this was proven for they did infact hold a large amount.
But then last year they did sell some of their holdings.
Elon has stated that he doesn't hold any bitcoin but I believe later it was revealed that he did.
It is hard to follow what he holds in any cryptocurrency because you some times hear he is promoting one thing and then another later on.
I don't even think he knows what he has as a crypto portfolio anymore.
