Have bought all My Realestate with fiat debt. They print faster than the loans. Made 10x on land in 8 years. At 6% interest. The payments are almost a joke. In fiat now.
Same for my duplex. 3x 12 years. 4%.
I’m about to do the same with BTC if this dip gets low enough. Ladder in on the drop. Some bank was dumb enough to offer me 0 percent for a year. And 13% there after. So. Yea. I’m doing it.
