Well, talked to the bank today about "selling the house for bitcoin", or to be more precise to take out a second mortgage, restructure my debts and "get some liquidity" as they put it. Good talk, and it's all settled. I'll be paying a llittle less each month, will have a substantial amount to invest in btc put in my account, and will also have a fixed interest rate for 20 years. Good times.
Of course they asked about what I wanted to the with "the liquidity", so i said I was looking to have some cash ready for when this whole cardhouse comes tumbling down, and invest in btc. That was a good enough explanation for them.
Nice bank. Crazy system. 1.7%.
FWIW, I support your decision, although it may sound risky. When I got into Bitcoin in 2015, I bought 0.5 BTC for a meager 100 . I had a large sum of fiat available at the time, but I chickened out, and only used 100 . Over the course of the following 3 years, I gradually (unnecessarily gradually) used said large sum of fiat to buy the remaining of my coin stash. Had I used the entire said large sum of fiat in 2015, I would now be owning 10x more coins than I currently own.
Lesson #1: Best time to buy BTC is
NOW.
Lesson #2: Buy as much as you can afford to lose (but not less).
Of course, you must be prepared to endure some potential setbacks (e.g., bear market of 2018), but even then, you'll be in great shape in t+3 years.
Not using my BTC buying potential in 2015 was the biggest mistake I've made in my life.
