They are still nascent so interest rates are high on them and reduced trust options are limited.
I had a B2x loan from ledn when we were below 20k. So in this product you post bitcoin as collateral and they buy the same amount of bitcoin for you to double your amount. You must maintain at certain collateral threshold. Maybe 30%, don’t recall exactly. Anyways I took a small one out 0.1BTC as collateral and got 0.1BTC. It worked out well as I closed it out around 30k and the issue price was sub 20k so after interest and principal repayment I got almost 1.5BTC back.
I closed it out early because I was concerned about Ledn when they bought a shitcoin fund in Canada. I didn’t want to take a chance they would start don’t some FTX crap with my bitcoin and I would get screwed.
