This is Natasha from InvestSpot.biz
I came to this forum from google search on the term of some hyip program's name.
I notice that more and more HYIP programs are accepting Bitcoin as one of its payment processors, and more and more Bitcoin users are trying to earn from HYIPs. HYIP Monitor InvestSpot is monitoring all the popular HYIP programs, providing the real status of their payment status. It is a good source of reference for you to avoid being scammed. Don't invest your money if you find a specific program is labeled with "Problem" or "Not Paying" tag on a hyip monitor.
Good luck.
What I like most is your RCB on hyip programs.
By the way, may I ask What is RCB?
RCB is a slang in the hyip world, it's "referral commission back" for short.
I joined a few times under https://investspot.biz but never request a RCB. How to make a request?
