I was just thinking that if that number or even the ratio stayed the same and one still needed 1000 coins to have a masternode, and Dash became used as a currency then the price would have to be a lot higher to provide enough capital.
Has anyone run any numbers?

Is there a plan to phase out masternodes or reduce the amount needed to run a MN?

I Dash ATM were to be used as a currency for say $10m of transactions a day then that would require the total volume of "free float" to be used eveey day. IOW there is approx $10m of Dash in circulation outside MN right now, so if being perhaps more reasonable. We wanted to see 10% of coins transacted per day and we allowed for 10% of the "free float" to be used each day then Dash would need to have a market cap of $200m.

Does that sound right?
