Well, a big difference is that you get a mortgage for the purchase of a house, and that it is not so free what you do with that money. In addition, you pay back a mortgage, including this one, over a period of 30 years. And normally you pay back a loan, especially those in the crypto world, much faster. Think of terms from 3 months to 2 years at most ... The amount involved is often much larger with a mortgage. There are, of course, other differences as well. But I haven't seen any contracts, so I can't tell you those either. I don't have a crypto loan, and I don't have a crypto mortgage.
