I wouldn’t suppose that people are required to inform steam that they’re dead. Therefore, I’d assume the easiest way to bequeath games/DLCs, etc, is to get a wishlist from your loved ones, and then gift all of those games prior to death on a credit card that you might not be able to pay, due to being dead. Steam gets the money, the CC company gets shafted. Alternately, share your credit card details with a loved one and that list, and have them order within hours of your death (this depends on whether or not you were plausibly alive when those CC transactions took place)
Microstrategy is an analytics company that buys bitcoin to pump bitcoin - they own something like 1% of the total supply.
Tether is a cryptocurrency that lets you do tax fraud by being pegged 1:1 to the US dollar, but can be exchanged in-kind for bitcoin so you don’t actually trigger a taxable event. It’s run by iFinex, a company that also runs the Bitfinex exchange. I’m not really sure that they actually have 120 billion in cash
I have no clue who actually runs these companies tho
