I've converted my EOS to REX and what else do I need to do to earn interest on REX? Do I get interest in EOS or REX and how do I withdraw this interest? Is the dividend daily or every minute?
Once you have buy REX token you just have to wait for the rex token price to goes up in the market with this formula
REX price = (Total Lent + Total Unlent) / Total REX
To withdraw the dividend you would have to calculate and sell just the amount of the REX price that has been added to your REX total
I think the extra REX is calculated live, so you get your gains every seconds
I got my info from this link and this is the best guide I have find:
Great picture of the whole system:
