most projects i see claim x% apy on their liquidity pool or vault etc using e^rate (continuous compounding)
hive on the other hand uses 15% apr, flat annual rate.
considering there's miscommunication in pretty much the entire world between nominal interest vs compounding interest, it's not really a big deal.
but maybe hive is somewhat oldschool and less fancy. whether that's good or not isn't so clear.
there's fancy projects that do 10,000% apy for a brief moment and then fall into obscurity within one or two years. hive to me is more like a zombie that doesn't die.
