Instead of trusting a DT1 member, thereby creating two possible points of failure, how about having a multi signature arrangement for some portion of the funds while theymos still keep some portion.
A timelocked fallback would solve the issue of what happens if theymos disappears, but multisig seems like a good idea as well. When he is active he retains full control, and if the coins don't move for a year or two, a small group of people, such as current admins or staff, can also take over. But there are a couple of problems: someone needs to move the coins periodically to restart the timer, and the setup is more complicated, so it would be best to test it out with small amounts first. He might have a plan he's just not talking about and even a brief answer of yes there's one would be comforting.
Some financial reporting standards require appreciating assets to be stated as income, but this is some sort of BS if you ask me.
I don't think this is BS as it's accounting versus tax. I believe fair-value accounting for crypto (US GAAP since ASU 2023-08, for instance) recognizes the gains in value, but for US tax purposes gains generally aren't recognized until you sell. So an entity can appear very profitable on their books, but not have any tax bill. I am not sure which standards are in effect within the forum but this is why a simple cash report (income/expenses, like theymos posted earlier) is more useful to the community than full accounts.
