Well, if you'd pay $900.000 intrest on a $100.000 loan over 20 years, you should switch banks immediately
I took a loan of €150.000 over 20 years when i bought my house 10 years ago, in the end i'll have to pay about €40.000 intrest, but i can deduct this intrest from my taxes, so in the end i'll pay about €20.000 out of pocket to loan €150.000 for 20 years (this are approximate numbers).
I'm a big fan of crypto, but i'd personally rather have a house to live in than a big fat crypto wallet... I guess i'm to oldfashioned Wink
I do realise i can get a lot more profit when i would have invested all my money into crypto, but you can't live in your wallet...
