- on the other side, by buying GPUs/ASICs/etc. they buy something that is totally unrelated to the coin, they can do evil to as many coins as they want.
The thing is people can also buy it to do good and give themselves 'power'. If you buy a PoS coin, you're restricted to that PoS coin. If you buy mining power, you have the power to support, build, create and mine/secure a coin of your choosing. The fluctuations in coin value and their short lifespans means you're generally better off using your money vote on mining gear rather than an individual coin. The ideals I prattle on about require lots of coins and lots of freedom to support the coin you choose. If NOBL becomes too decentralized, too corrupt or you don't support the direction it's going (as many may not) then you can point your mining power elsewhere to support/mine a coin you want. Right now of course practicality drives that decision more often than not. Which means we also need to appeal to non-miners, to keep miners with us. There are many variables at play.
- on one side, by buying a PoS coin, they (evil dudes) actually raise the value and they would probably not want to lose value when they decide to dump (although I know there may be very malicious people willing to suffer loses in order to do evil).
Also one thing to factor in here is the 'evil dudes' can more easily artificially raise the value themselves since there is no new supply coming in. They also may have gotten in at 0.5%-1% of the current price, so they'll let the value climb as high as they like/feel they can handle until it's time to dump.
