Thanks for your interest.
We are going to make money the same way as investors are - by leasing mining power, we are going to be paid in RIGGS. Those riggcoins will then stake, and we will profit from the staking.
This is something like a dump-proof strategy. Investors won't have to fear the developers dumping their coins, because if we dump, we are essentially giving mining power for free, which is a loss for us.
