Hello, I am planning on investing on this HYIP: http://www.forexavail.com/ If you take a look at their investment plans it includes the following options: Investment Plan 21% 22% 23.00% 24% 25% Minimum Amount $5 $1,001 $4,001 $8,001 $12,001 Maximum Amount $1,000 $4,000 $8,000 $12,000 and more Investment Duration 5 Days 5 Days 5Days 5 Days 5 Days Total Profit ( ROI) 105.00% 110.00% 115.00% 120.00% 125.00% Principal included in your daily earnings. We will not return the principal at the end of per term. System pay profits to members account on Business Days ( Monday - Friday ) Compounding is not available. ----- Since I am new to HYIP, I would like clarification for my following question: It says I would earn 21% daily but without principal (I assume that is the amount I invested in). So would that mean I really would only earn 5% extra of whatever I decide to invest during 5 business days or?
