At last we have found 2 hyips that have more than 2years statistic. One is engaged in stock index trading, the other is in yahoo groups since 2002. Amazingly they are not known publicly probably because of its unattractive low return below 10% per month. But at least it prove that real hyip could survive more than 1 year if it sets return between 5-10% per month. More than that will diminish sooner or later. So it's up to hyip investors to choose getting rich quick hyip or getting rich slow hyip. If they choose getting rich quick hyip, they will be scammed quick also.
