It's funny to see people complaining about only getting 15% profit...where else can you send $1 and get $1.15 back with no work or risk?
So true. This is close to the "money growing on trees" saying and some users still find reasons to complain. These are the type of people that if you give them money for absolutely nothing they'll still bitch about it. They should go put their money in the bank or stocks and see what profitability they gain from that.
