Well sure, if you want to spend all your time doing it. I suppose I should have qualified my statement that one shouldn't expect to make significant amounts of money from CashCrate unless one essentially makes CashCrate a full-time job. CashCrate seems to be a fairly easy way to make a little extra money, but NOT an easy way to make a LOT of extra money.
I'm not saying it's a bad thing, or a scam. I just mentioned that one probably shouldn't expect to earn tons of money in their spare time with it, is all. But who doesn't like making a few extra bucks?
