5 percent is definitely more resonance and realistic than 10 percent scam out there
yeah but principal back? .. not believable, not for long term..the 10%'ers don't offer that.
btw, ive moved all of my "investments" to sites running over 6months. 20 days @ 8% / principal returned. I admit I've made a bucket load of btc with 10%'ers but the script is our there, only small variations and every noob scammer and his dog is opening a hyip site. Parking my funds in something more stable for the time being.
**sits on fence for a while**
