This is a positive feature that responds quickly and accurately to market forces. What sense does being stuck with some other miners difficulty make after they have left the chain? The real abuse of difficulty comes when someone with large hash power jumps on a chain like LTC or BTC where the retarget is measured in many days. For the first number of days their immense hash power gets to abuse the low difficulty and mine an extraordinary amount of coins. When the difficulty FINALLY gets around to adjusting, they jump off, leaving everyone else to suffer the higher difficulty for a long period of time while they wait around for it to retarget, when the larger miner jumps back on and abuses it for another stretch of time.
With TRC large miners get only a short window of opportunity to abuse low difficulty, and small miners only have to suffer a brief period of time after large miners jump off the chain.
It's more fair, more responsive and more egalitarian. Free market in action.
Wow okay rabbit I guess you are really a die-hard fan that has to defend every bug of terracoin as a feature. It's a short windows yeah but it comes every hour so if you add them up suddenly it's not so short any more. I am sure large miners can afford to tweak their programs to only mine terracoin every other 30 blocks, while the smaller miners suffer.
Maybe someone can start a pool to take advantage of this, just to show how ridiculous it is to claim this as a feature.
Actually it's one of the things that really did attract me about TRC, no kidding. I'm a small miner myself and I was frustrated from the previous LTC rise when the difficulty went up significantly from some exceptionally large miners that came on board, but whom left as soon as the difficulty went up leaving us with a few days of frustratingly high Difficulty. I know I'm not alone in this, the BTC-E chat box had lots of small miners grumbling and watching litecoinpools retarget estimator, just waiting for it to go down again.
I'm not saying that you couldn't be right regarding having this exploited by a miner or pool that regularly jumped back and forth, although I think the effect is much more pronounced right now because the hash rate is relatively so low so relatively few large miners jumping on really makes big waves. When the rate is (hopefully) might higher and the number of miners much larger, I'm would hope that this effect won't be so pronounced.
That said, many of the big miners seem to be jumping on when the diff is low and profitability high. They in general seem to dump their coins pretty quickly, which adds more coins into circulation, which i also think is a good thing. It's more important to get coins into as many hands as possible at this stage of the game. Small miners are more likely to hoard (in my opinion) given the small number of coins we make. Large miners, even if only mining monetarily for the profit, are a helpful part of the economy.
