I think those who have lost all their coins on ShareX - it dumpers.
And if given the chance again, they will do it again.
So, a new coin need to exchange for old coins. Then they will go only to those who truly appreciates the work of the developer and the community. IMHO.
Actually I expect a decent number of those who lost their coins on ShareX were people buying more coins, not dumping. If you dumped, you had no coins to lose anymore. I'd guess a lot of those who had coins there typically were buying more, or doing the 'sell high/buy back in low game,' for even more coins.
