Hello @christian
For coins like $ETH (-1,38%)
$ADA (-2,07%)
$AKT (-2,19%)
$DOT (-2,23%)
$AVAX (-1,71%)
$MATIC (-0,72%) 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.
