It is hard to beleive that some hyips are something more than just a lottery scheme, which gives profit to those who catched up to join and win before it is destroyed. Some of them can be even dangerous. Like seven-million-dollars.com, which contains a fake link to Liberty Reserve site. Admin is so greedy as to collect investors money and trying to steal their own funds from their accounts. Please be extremely careful with short-term HYIPs and always check out all data while processing payments.
