For example, the current block reward is around 14 xmr - better to change it to 7 xmr.
It will help the dumping pressure and gives nice and steady growth for the coin.
The existing balances and total number of coins should not be touched but just give 100 % more time for the rest of emission.
Some would call it a community-fastmine. Not like I'm saying it's fundamentally bad, but it doesn't look clean.
If something like that were to be done, and I'm not saying it is even on the table, it would have to be for better reasons, like the long term viability of the coin. Every time the issue has come up, though, it is always presented as a way to manipulate the market. That is a total non-starter. We could convert to a PoS shitcoin if we wanted, and not have to deal with any dumping at all. There is zero interest in doing that. Move on to one of the 1000+ of those if you want to be free from dumping.
