some developer can make good profit on it, but only if he works, deliver and hold.
Agreed.
i think your 1860 coins must be sent to an escrow
only deliver to dev if real work on the coin
The escrow could protect ... the CoinDev from not getting paid.
But the investors need to be protected too. Namely from a CoinDev who does not deliver in the end, or bails prematurely.
Let us work out a scheme, in which the dev funds will be released step by step.
