Any of these are on coinmarket.io? You can generate new wallet address with every new deposit right?
How is the selling on coinmarket reported on the blockchain?
If we manage to takeover premine needs to be invalidated if possible.
Selling on an exchange of course is not related to a blockchain.
E.g. all these coins can be sold atm, but new holders didn't withdraw them from the exchange.
Coins can be destroyed only if the exchange confirms that these addresses do not belong to it.
However my guess that half of premine or so was dumped.
