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.
Yes I like this your strategy. If pos price is low, convert your lending interests to from USD to POS, if price then pumps again, convert the POS to USD and you can reinvest it if you like or wait for pos price to come down again so that you can buy more pos and you have more tokens than you started with
