It'll be very insteresting when mining becomes unaffordable for most users. I sure aint going to risk sending thousands of dollars to an unknown company in the hopes of getting decent mining gear on time.
PoS (Mintcoin) may be the way of the future?
PoT seems a bit too random and unstable.
I love Mintcoin for that reason. I've been mining for a long time and this arms race keeps getting worse and worse. I had expensive video cards that are no longer good for mining now because of ASICs.
I found Mintcoin and now I make a couple hundred dollars profit every month from just minting and I don't have to have air condition on either. My GPU fans are not blasting like a jet engine, so it's been quiet at my place. Mintcoin is the way of the future and the environment and Mother Nature will thank us for that.
