A question to the dev: I would like to know what happens if some big ltc pools (or other scrypt mining pools) used their hashpower to 51% attack DGC with the intent of killing the network.
You know as described here for example:
http://maxminer.files.wordpress.com/2013/06/ftc_51attack.pdfI just had a discussion with someone who says that DGC would need to have a much higher hashrate to be secure (he compared it to ltc) and then I thought well, what would happen if people switched from mining ltc to other more profitable coins and ltc hashrate went down? Would it be made just as insecure again?
What happens to scrypt coins in general if people are sick of using gpus for mining because they cost too much power or whatever reason. As there are no Asics for scrypt...nor fpgas at this moment.
Why a would a pool attack digitalcoin? Large pools benefit from alternative currencies because they lower their own difficulty and smooth the fluctuations.
You can only duplicate the coins you own in an attack. I know of no major DGC holder willing to risk destroying the value of his coins. What would be the incentive to attack the network otherwise? The incentive for the FTC attack was money.
Yes, LTC, like all scrypt and sha coins, is secured by hashpower. If the power drops, so does the security.
Finally, GPU owners are moving to scrypt mining and not away. ASIC are pushing them in that direction at an ever increasing rate. When bitcoin difficulty stops rising exponentially, and scrypt starts dropping in profit instead of rising exponentially, I'll start worrying about what will happen in the event of a GPU exodus. GPU mining cannot randomly drop in profitability, and the more viable choices a GPU miner has, the less likely it is he'll just give up on it. It is after all a market of supply and demand, at least until ASIC are involved.
ASIC are not an advantage in as many ways as they are. I'm not a fan.
We've gone through a nice jump in price and activity lately. I can see further spikes like this occurring over the coming months... I would list the reasons why but you already know them lol.
