LOL. I'm pretty sure affandi meant something else, probably daily yield on a 600% to 700% annual rate. After all, APR means Annual Percentage Rate. The annual rate could be true, 600% to 700%.
I know what OP meant, but that's still a rate that seems way too good to be true in my eyes, at least from an income standpoint. I realize that lots of people have made much more than that by holding coins and achieving capital gains above 700%, but that's different. If a staking coin promised that much of an annualized return, I would be extremely skeptical to say the least.
Doesn't anyone else find that claim to be a bit odd, or am I just completely out of the loop? 700% is almost 2% daily, and there's no asset I know of that pays out that kind of income.
