Disclaimer: zero money in this market. Dump and run. I don't trust other people to play ball. The ship is gonna sink, get out while it keeps you in the green, reinvest in something more stable. I wouldn't feel the least bit bad for triggering the crash.
An asteroid mining game in the style of shipbreaker, possibly same universe. The asteroid(s) should be more realistic in that they are far apart (maybe closer if you're mining in a ring, Saturn?) and surface is gravel-like. Cost-benifit of mining and returning certain materials, or using them as needed.
So China and Iran tow Russian vessels around as a military exercise. Sounds like good practice for a future alliance. I recommend developing a good way to cut away a sinking, possibly burning Russian vessel.
The 50k and under untaxed I disagree with. It sets up for a possible scenario where those who are taxed get priority in policy. If you are able to be a productive member of society, you should pay taxes to support that society, and the infrastructure it provides.
Most of the others in the list I agree with or don't know enough about the case to comment
Do these people not realize that the first thing a new regime usually does is put any person who would be a threat against a wall and executes them? Are they convinced this will be different or that they won't be that person? My history education may have been lacking, but that was very clear.
I'd like to be a millionaire, but that is an method to achieve another goal, not the goal itself.
I'd like to vertically farm algae on an industrial scale as an atmospheric carbon sink, and additionally see if there is any way to do so profitably while remaining carbon negative. 1 million dollars would probably be enough to construct a small facility and hire the staff and experts I would need to figure this out.
"Millionare/billionaire" as an identity should be an insult.
Anybody with an industrial mindset will bare minimum want to take any large amount of liquid asset and turn it into production. Build and improve factories, fund research, improve living conditions near your operations. Having money acruing interest can be part of that, but should not be your primary revenue stream.
Oh no. Anyway....
