I am only wondering if there will be a sale of 200 genesis address again, why can the dev do that?
If this will be the case, can he make and make genesis addresses of this coin, thus creating money on thin air?
The addresses will be in the contract, which can not be changed. All previous pairs of addresses are transferred to the new contract + 200 pairs of addresses that will be purchased.
And anyway, if we are to reason like this, then any tokens are money from the air.
