with this your username, I can assume that you come from russia, people from russia are very involved with hyip and exchange and scam sites.
do you have any experience scamming people? I mean, it's quite difficult to start an hyip website alone, without knowledges and a good team.
Many scammers who are hyip site admins have one or two people in their team and manage to manage the ponzi/hyip site for at least 2 years, of course it depends on the plan that the hyip, the budget and the place where they make the site advertising... In general most people are aware that hyip sites are ponzi scheme and created by thieves. even knowing that, these people invest in these hyip/ponzi sites. Is a very regrettable situation
