Then I previously warned about doing a coin swap for Greencoins because this will put 6m coins into the market instantly. I see the warning was not heeded and the coin exchange is going ahead. The Greencoin holders have lots of bags that they currently cannot do anything with. As soon as the new coin hits the exchange and the price goes over 167 sats, they will dump the 6m. Some may even dump earlier because at least they can get something out where currently they can not get anything out. The 6m can almost be seen as a premine, with the premine in this case being handed to the public with no anti-dumping control like escrow. I cannot see any economic justification of doing a coin swap. Greencoin holders should rather take the hit on the nose and move on and start this coin from scratch.
The above means that there will be two highly concentrated groups of holders that will have the same objective and that is to sell to make a profit or to get something out. This gives a high risk of a dump fest and sell pressure that will kill the coin. I would suggest that you scrap the idea of doing a coin exchange and that you use a different algo than X11/13/15.
If you carry on like planned, fine, it is your coin, and there is a chance that you can actually pull it off successfully e.g. if the large farms look the other way or if the old coin bag holders all decide to hold and not to sell for at least 10 months or so. After doing a risk assessment though, the chances of the above scenario playing out is higher.
excellent write up one of best ever I have seen on BT
