I know how SAI and the new vault system works.
I understand that before, you could lock the ethereum in a CDP and get the SAI (DAI, back in time). Than by lending the SAI (still DAI back in time) maybe in compound you could not break even because of the stability fee.
I see in compound or fulcrum it’s possible to deposit SAI and get an interest back, but the interest rate for ETH is too low, now at 0.2%. Maybe fulcrum is a bit higher (why? Because less audited?). But still…
So if you have ethereum and you want to keep them but at the same time earn an interest, how can you do?
