is that normal that i can only reinvest 100usd if I activate the automatic function. I thought I can reinvest every USD I earned from lending
The minimum you can invest on the PoS Lending Platform right now is $100.
You can always stack your USD gained from interest and whenever you hit the $100 invest those again.
I'm stacking the USD I get and converting them to PoS whenever it's at a low price.
