Wow! That's an amazing return! Yes, there are other lending platforms like Nexo, Alpaca Finance, Qubit where you can lend against your own assets. I would just say be careful with assets that are not over-collateralized, because if the value of the underlying drops below your margin amount, your underlying asset can be liquidated by some platforms in order to pay for the temporary loss in token value.
I've seen some people take out loans from their own holdings in order to re-stake somewhere and earn even more interest. It seems like a good idea on the surface, but I do not do it due to liquidation risk. I would rather just use my own small amounts of capital and compound gains. Likewise, I like to earn major coins like BUSD, BNB, BTC, ETH whose token values will not likely go to zero.
Congrats on your earnings! I'm excited about DeFi too! To be truly financially independent, I suggest to others to pay off variable expenses like credit cards, auto, and mortgage if possible, then have a cash emergency reserve of at least 12 months, before considering leaving a stable job and living off of crypto income. I've got an article about how and why to do this called When You Can Quit Your Day Job?
Thanks for reading! Keep me updated on your progress! :)
