I have started testing out a HYIP program that involves Dogecoin and so far they have been paying out very well.
The way it work is you deposit some Dogecoin (minimum 300) and then you get payed 5% every day to your wallet.
Check out this photo of my recent received transactions - they are still paying as of 3/9/2017.
At this point is like I am getting free dogecoin every day - I have made back my initial investment and I also got 1 referral that deposited and I got an 8% bonus from that.
I still think they are just paying people with the newly invested Dogecoin like most HYIPs do but so far it has been ok for me.
Follow me if you want to be updated on how this goes.
Have a nice day !
