Selling 50 masternode is too much. The intention is always to fill in own pocket, huh?
You dont need that much funds to make this project work.
With current difficulty and block reward, coin estimated at 0.000015 btc each.
1 masternode may cost around 0.15 btc once it is listed in an exchange.
Buying masternode from dev at any price above 0.15 btc is like giving away your money to dev.
Even if dev really do sell 1 masternode at 0.15 btc, 50 masternode will earn dev 7.5 btc.
More than enough to get 1 coin listed in the exchange and masternode online.
Just one man calculation and estimation, guys.
Hope it open your mind and not to get scammed in our investment.
Happy mining, happy investing
Going by your calculations, one can conclude that its better to wait until coin is listed in the exchanges before buying the Masternodes. The case might even be worsened with all the ASICS being thrown at the coin alongside the numerous mining pools supporting it already. These miners will just be accumulating it and waiting to crash the prize like they did Aerium and so many other coins. The network rate is shocking for a coin that was announced for such a short period of time
