There was no exploit of special kind with FTC, it is just classic old "mine it until it's the most profitable then abandon the train" issue. Terracoin experienced that and got hurt badly
but it is fixed, which is not true for any other coin. Not sure if developers are affraid of hard-forking blockchain or not, but lack of action will inevitably lead to catastrophic outcome
sooner or later. Even BTC developers are playing with fire there.
You don't seem familiar with the history.
We are not talking about any special exploit, it is just that while one is in there fixing the problem namecoin ran into, which Terracoin and Feathercoin recently also ran into due to not having already had the fix ahead of time, you might as well also fix the timetravel exploit.
If Terracoin's and/or Feathercoin's fix for the problem they recently experienced, that namecoin experienced before them so long ago, does not include also fixing the timetravel exploit while they are in there changing stuff, then they are simply setting themselves up to be hit by the timetravel exploit. Just like they set themselves up for what they just experienced, which is simple chain-hopping, the same thing namecoin experienced, the same thing nearly all the coins that existed back when namecoin experienced it promptly fixed so that it would not happen to them.
If Terracoin and/or Feathercoin left out the fix that would have prevented them suffering the way they did when chain-hopped, how confident can one be that they included a fix for the timetravel exploit?
So, again: chain-hopping has been known to cause what Terracoin and Feathercoin stupidly suffered, which is why almost all coins put in fixes years ago so they would not suffer like Terracoin and Feathercoin recently did.
Terracoin and Feathercoin are thus way late to the party when it comes to fixing chainhopping, they are NOT the only chains that have fixed it, they are the idiots that left out the fix in the first place.
Are they going to wait until they are attacked by the time travel exploit before fixing that too, or did they at least include the timetravel fix along with the chain-hopping fix like most coins did way back when most coins fixed chainhopping?
