It does impact long-term investment. If you expected the market price to be 10k, than you will adjust your target to about 8200. Like I said, the risk/reward on this coin is still very favorable even with the total coin adjustment. You have the option of selling if you think it's overvalued. I'm not grasping at any straws, you are. If you read my post above you will see that I said the dev needs to explain.
The market will adjust by 20%. Anyone who owns coins just lost 20% of their investment. Tell me again how 20% inflation and an extra 4-5 million coins is grasping at straws.
