How good does it seem to you?
there is something similar. On cexio exchange, you can take a loan using balances on their platform as collateral. but at the same time, they have a staking program, where you don't have to lock up coins. Even if they are in order, you will get profit from staking/holding on there.
I haven't personally tried it, but it closely looks like your scheme.
They do provide loan but can't find a option to loan with staked coins. Plus they do have risk associated of loan liquidation. Which in our terms, is no risk associated. Our team still can't find a competitor providing same services.
Thanks for the feedback!! cexio exchange is best for beginners: we are saying cash app.
