The $250k FDIC limit has been a bit of a joke for decades. If the bank goes under, FDIC covers all deposits, basically everything.
Wow, that's a very interesting take. One I'm very skeptical-of..
Open a Vanguard account put most of it on VTSAX their total stock market index.
I try very hard to avoid investing in anything unethical, and when I look at the holdings of VTSAX, I see Apple, Amazon, Meta, Alphabet, Tesla, JPMorgan Chase, Exxon, Walmart. Fuck, they're even holding stock in UnitedHealtcare.
My biggest concern about Apple, Amazon, Tesla, and Walmart is their history of abusing workers.
Bitcoin uses magnitudes less energy than the financial industry companies, it doesn't use any additional energy as it scales-up, and most of that is renewable energy. So bitcoin is definitely the ethical option for the environment when it comes to non-physical money (despite the disinformation on the net about this).
I prefer to put my money in credit unions (non-profit banks in the US) that do not invest in war, animal exploitation, or fossil fuels. Most credit unions loan out their money to their local community to support small business. That, bitcoin, and buying stocks in other ethical companies has been my approach to ethical investing.
