You can't "go bank less" with Bitcoin, because you can't buy food and pay the bills with Bitcoin. Sad but true...
The Federal Reserve will step in and provide enough liquidity for the bank, if the bank really has problems. The NYCB stocks dropped, but that doesn't mean that the bank is insolvent and the depositors will lose their money. We don't need such unnecessary drama and clickbait news.
We might be seeing more news like this, mostly because of the high interest rates in the USA. The same drama happened last year with Silicon Valley bank and Signature bank and everyone was a expecting a big financial crisis in the US, but nothing happened and the US GDP has a 2.5% growth for 2023. I think that the news around NYCB are basically the same clickbait FUD drama.
This is a pet peeve of mine. People talk about how you could be "bankless" but the reality is that I can't spend bitcoin everywhere I go, I still need to spend fiat, and that means either I will have to have cash, or have a bank account and a card.
If I want to go with pure bitcoin, then I would also only have to buy things I can afford with the money I have at the moment, and never make a debt, which makes no sense to me since I would not be able to buy most of the things I have. Hell, in a sense I can't even pay my medical bills, because they are a lot, and just recently I took out a 2k dollar loan to pay for something, and how could I have done that with bitcoin if I didn't worked with a bank? It would not be possible at all.
