Yes, a lot has changed over the months. LEO migrated from inflation to deflation and now native on arb. LeoDex is there doing big things and you can stake Leo on Leodex after bringing to arb to receive sLeo that you can stake to earn USDC.
That's the little my knowledge can give about it.
Any idea ,how much USDC a month , 10K LEO will earn?
No idea, we will definitely know more about in two days from now.
