read the forum i'm picking up on, people who lack ability attempting to modify code they don't really understand, and by the adaption of the coin could totally ruin the coin, it's called Primecoin, for a reason. due to the way it's coded and it's more complex than to let someone come along and try modify it with a limited ability and skill. you'd have to be proper good, and i'm not getting that vibe from what i read here. you'd cause more damage by screwing it.
Its not that easy to manipulate primecoin as most other old coins since it is much better distributed. For other coins "scammers" could easily buy 50% of the coins, do a "relaunch" and dump on the new "investors". I hope this don't happen with primecoin.
if the is no cap on this coin it might need a cap at some point, but only when we see a massive price rise would or should anyone consider a move like this, and i don't think it's any time soon. code in a cap at some point i believe, but no time soon, the only good idea is increase adoption, and use cases, before anyone considers a cap. it's a good coin due to it's maths formula, but i still think it might have to have a cap in the future, because at some point the will be to many. and you will no longer have to keep minting coins, the is a limit to everything.
i get the impression people don't like caps, but at some point you certainly have to cap the supply.
