15 Masternode, 0.7 btc each
Easy 10.5 btc (minimum)

The problem with dev nowadays, they see masternode coin as easy way to fund their cheap project or a way to get easy profit.
Even if they dont scam investor, they may not have the will to strive when the hard part or problem come.
Its easy to abandon the project when the funding dont come from their own pocket.

Dev should keep the premine and fund the project using their own money. Dump little by little once the coin is successful.
This will motivate dev to work hard on their project.

Dont support project with no clear roadmap that demand insane funding, boys.
Be wise when you are investing.
