Just to reply to some things you're saying.
I don't think it's over for Bitcoin but Bitcoin definitely needs to improve soon.
Fix your fiat situation first, pay off debts, build an emergency savings fund then buy Bitcoin, and Monero.
Realistically I'd say probably 5% to 20% of your portfolio should be Crypto, stocks for compounding wealth, gold for appreciation, Crypto for protecting your money from the government.
Bitcoin won't make you rich, Stocks won't make you rich, Gold won't make you rich.
Consistently investing, and planning for your future will.
I'd also say explore Goldbacks if you're interested.
It seems like you understand Bitcoin but it doesn't hurt to touch on basics from time to time.
Bitcoin can be used in the same fashion as cash can be at most major stores with the right wallets like Gemini, and Coinbase, Cake Wallet, and Strike.
It's easier to live off of crypto now than it's ever been.
I hope when you're ready to explore the crypto ecosystem that it emboldens to be a sovereign individual, and live your life without fearing the government.
I hope for the best for you 👍.
