The voting is kinda pointless imo, exept to make the "curent" comunity feel important maybe. Something i find rather pointless considering how few and relatively unimportant they(me included) are and of course how dedicated they are.
The amount and price should be determined by the amount of demand existing at this moment.
I know that everybody would like MTR to be worth 120k sats NOW. It isn't. And putting a very large amount (400k coins) on the market without a huge(expensive) marketing campaign won't drive the price higher.
Considering that the need for cash is real, the amount of MTR that should be put on the market should be less then the demand(to generate a price increase), which of course can be very hard to determine, but it should be less then the amount that the "real" investors(identified by mastertrader777) are willing to buy at this moment.
As for my vote, 200k should be enough imo.
