So, nothing will be changed, we will have 2 coins with mostly the same relations, % of supply, between owners.
And we have to prevent dumping.

We can't prevent dumping of one coin. We will have another chance to fulfill our holy duty.

Fun is here.

Why?
Why for crying out loud do you have to prevent dumping?
Let the dumpers dump, let the fools give their coins away for basically nothing.
The thing is, dumping can't go on forever, because the coin supply is pretty limited, so this will go away naturally.
Just wait.
It just boggles my mind that I hear people here talk about new features they want to implement
to "PREVENT PEOPLE" from doing whatever the hell they want.You don't prevent people from doing ANYTHING in a decentralized economic system. That goes against EVERYTHING satoshi ever dreamed about.
Don't mess with freedom.
If you think that dumping is stupid, do the following:
1)Buy those coins for cheap. Sell them only at a much higher price.
2)Mine coins yourself, to take coins away from dumping miners. Sell those coins only at a much higher price.
It's THAT simple... no restrictive coding required.
(Again... this notion of "restrictive coding" inside of decentralized cryptocurrencies... it baffles me... it totally baffles me)
I ironically commented previous post.
I do so what you suggested, more or less.
