I think using fiverr for money is great. But is not so easy to find a gig that can make fast money and attract people. I've dealt with fiverr for money several times; and bought different books and programs to make money with fiverr.
I really could not make any money at all. I think a few people are successful with fiverr and collect most of the cash.
Another thing in fiverr for money is its delaying money to withdraw. It takes about two weeks to get it from them.
But generally, fiverr for money is a great website because it is a good idea from the start.
Hope this helped.
