If you do a $10010 loan and cash the daily interest out, by day 84 you would have cashed out all your money and are playing with the house money.When people say it is all going to crash down and everyone is going to lose a lot of money, surely it will only be money they could afford to lose and if they cash it out first they don't lose at all.
It really depends on average daily profits. For example, last week average profits are ~0.6-0.7%
Also typical cryptoinvestor tends to start with small amount, see it working and then up the ante. That's a natural behavior but also a thief of time because nobody knows how long it will last.
So I believe that it's more important to decide how much you're ready to lose, not how much you'd want to earn.
