More emissions could mean more coins on the market therefore driving the price down. However, some investors chase high roi coins and therefore the higher roi could attract more buyers and drive the price up.
I hope that it will still be possible to attract new investors, otherwise the old ones will suffer losses.
Given such a high roi, I think that investors will on the contrary receive a daily profit. It all depends on how much the price of the coin will fall, and whether it will fall at all.
