Hello @christian
For coins like $ETH (-2.69%)
$ADA (-3.79%)
$AKT (-4.86%)
$DOT (-4.06%)
$AVAX (-4.26%)
$MATIC (-3.3%) and possible more.
An approximate "%" APR/APY with your monthly or weekly reward would be a very good implementation as these currencies are increasingly more popular + higher marketcap. (BTC and ETH adoption these days)
"Worst" case APR/APY can be configured by the own user.
It would be a feature that separates the application from the rest for the better, pretty clear.
If more feedback is needed I can help ofc.
