(My opinion a person should have the basic commonsense to avoid such schemes)
this is a cancer, see how the system works:
The doube site promises high returns and promises que Those who bring someone to the site to link to (referral link) won 10% of the deposit of its Indicated.
see an example:
The john see a double site that promises to return 200% after 4 days and 10% referral commission
The john create a blog/site, create accounts on Twitter and Facebook and disseminates the site " double bitcoin 200% in 4 days ". john knows this double site will not pay for all investors, but John will earn much money from the referral commission.
If John has 1000 referrals and These 1000 referrals make large deposits in the double site? john earn 10$ commission for each referral, john has a profit:
1000 referrals x 10$ = $10.000 profit. if john has many hyip sites to publicize? john will win much money.
Many people not have character, just think of the money and disclose These shitty sites.
Today we are full of shit site, are self called "HYIP monitor site" all crap sites
