-if we can estimate when it will be an HYIP SCAM, then investing in HYIP will not be too terrible. 30 days old is old enough for a HYIP site. If you've been investing for 30 days, or you find a HYIP that he was already 30 days, you should not need to invest more there, and looking for a fresh new HYIP.

if you want to get coins easily, you can take advantage of HYIP, because like you said, that many HYIPs only pay a small investor. HYIP is definitely not a good place for a great investment. If you have a lot of money, should you invest in the real sector.
