I read the whole thing, it's textbook ponzi scheme ... why are you defending a system which is destined to collapse? I'm simply warning people not to invest too much into something so unstable, if you want to waste money on things that don't give you returns ... invest in stocks with Greek banks.
Did it not cross your mind where the money you invest goes to? Either this JustBeenPaid company invest it in other things, or they hold on to it/trade it into different currencies hoping that it will return a profit over time.
Did it not cross your mind that if JustBeenPaid ever runs out of money, your invested money is stuck inside of it?
I'm not doubting that money can be made from this. It's just that it will not last forever, ponzi schemes are like a house of cards - one gust of wind and it all falls over. That's why I warned people not to invest too much money in it ... from google'ing I couldn't find anywhere that the company behind JustBeenPaid publishes financial information, it's impossible to tell how well this company is doing (unless you go on website traffic alone) ... maybe the house of cards will fall down tomorrow, with thousands of $ invested in it ... maybe it will last 10+ years? It's impossible to tell, that's why they are so dangerous.
Why choose to invest in this thing anyway? Surely you should just invest in stocks; that way at least you have the law supporting you if foul-play happens.
tl;dr - Get rich quick schemes never work; ultimately people lose money due to their own stupidity of investing huge sums.
