You're certainly in the wrong forum for contrarian opinion.
There is no question of the devaluing of fiat currencies. The best "safe play" against this is owning DEBT in that currency, for as long as possible, and refinancing to lower interest rates as available.
In my opinion, despite hundreds of hours of Bitcoin podcasts, articles, books, etc. unlike the Bitcoin network, the future of Bitcoin's value and salability is not as certain as many here believe, so I wouldn't make myself dependent on being able to sell off BTC to not live on the street. But neither would I want to have 0 bitcoin. (EDIT: 0 point something is OK, I meant none at all.) I would spread my risks.
(The future of the housing market, however, is certain to crash, the only question is when.)
Bro.
There's a major understanding to take place here for you. Respectfully. If you want to be normie, middle class poor for most of your life, pay off your house and own zero bitcoin.
If you want to be extremely wealthy and in absolute command of any and all resources you desire to live the most magnificent life, keep as much debt as possible and instead of PAYING OFF DEBT (like a dumbass that does not understand the fiat economy, forgive me), you stack fucking bitcoin with all the debt you can. This means maximize your mortgage, long debt everything, don't pay a cent more than you need to any loan, even learn about disputing loans and mortgage fraud if you have the time and seek to legally beat debts without paying them anyway, sell everything you don't absolutely need, sell your 401k, roth iras, gold, etc etc, and hold absolutely as much bitcoin as is possible.
If all that sounds too crazy/radical to you, you haven't studied bitcoin enough, and you can take a lesser approach to my suggestions while you continue to put in the HOURS studying bitcoin to the point where you're all in on a bitcoin standard. This is the way.
TL;DR keep your fucking debt as long as possible as stack your fucking sats. Refinance your house into more debt as much as you can handle and lump sum ape it into bitcoin. HODL and WIN.
House prices are massively inflated (2-10x depending on the location of the house). I remember people saying in 2007 (before the last housing crash) that a particular house was too expensive at $300k. This year, that house is valued at $650k and nobody says it's too expensive. People across the planet (US, China, Europe, Australia, etc) are irrationally optimistic about home prices and they will soon begin suffering greatly for their irrationality.
Because housing prices are about to decrease substantially; the crash will begin within the next 24 months. If I had a mortgage on a house, I would sell immediately. Waiting to sell would be dangerous, because timing the market is how you lose everything. (The market punishes arrogance.)
It doesn't matter what Bitcoin does, because the alternative is that you could lose your house in foreclosure. At least if Bitcoin goes down somewhat, you still have something to sell. Moreover, Bitcoin's track record is far better than houses, accounting for the ups and downs of both.
If you do sell your house, you have two options:
Sell the house for fiat and buy Bitcoin via a KYC exchange. The government will impose an annual tax on any KYC BTC, so to do this and keep your BTC, you will either have to move into a van or leave the country (i.e. move to a country that doesn't extradite to the country where the home was sold). And remember, tax bills don't expire.
Offer the buyer a discount if they pay you in BTC. The discount will have to be steep (10-25%), but that's the only way you're gonna get that much non-KYC BTC at once. A critical aspect is that the buyer must put a fiat amount on the purchase agreement. If they put an amount of BTC on the agreement, then the government will instantly know how much BTC you received -- which is the same effect as buying KYC BTC.
Getting wealth is hard work. Keep that wealth is hard work. Losing wealth is as easy as accidentally telling the government you are wealthy.
