You may invest in ponzi schemes that give 3-5% daily. Also you can find many HYIPs that offer you more than 10% daily for 30 days or 25%daily for 5 days, etc. It is not real interest. Do not believe in such HYIPs.
Scam HYIPs are run on ponzi schemes. A ponzi is an illegal pyramid system in which higher level members are paid with the investments from newer members. They actually have a short life time. Many people lose money in these scams. Their websites are made from cheap old regular common templates(not a professional & unique design), anonymous contact information, give high interest rates(>3% daily is suspected as a ponzi),have an attractive referral system, etc.
Invest in still higher interest paying HYIPs if you can risk higher. HYIPs such as 7% daily for 60 days or 50% daily for 3 days are real scams. However if you are lucky, you can be in great profits provided you invested while the HYIP was just new. But risk factor is also very high and I suggest not to invest more than 40$-60$ in such high risk HYIPs. It is always better to avoid them.
