I don't know the profit. But i found this in the discord channel.

(as a masternode owner you have the power to make decisions on what genesis and the genesis network platform perform in the future. everything from development to marketing and everything in between.
beautiful thing about our masternodes is we have a "high" requirement but it does a few different things for us. we've calculated the amount of rewards per block out as to make masternode owners happy but not give a 40000% or ridiculous number roi
and since the requirement is HIGHER, even if 100% of all the coins were locked into masternodes at this exact moment, that'd still be less than 200 nodes)

I think this is very nice too know.
