As for quark, insiders either do hold massive amounts of they don't. It's not a trivial question. I have read they do which is a deal breaker for me.

What do you call massive amounts? If I recall you own a "massive amount" of IXC......

3% is not massive, especially when I paid cash for it.

Rumors are quark insiders own close to 80% and they didn't pay a dime for it. That means they will dump on anyone on any rally.

Huge difference.

Will have to agree with you here. The way quark was designed, there was massive mining in the first 6 months. to the tune of 240+ million coins. Then it drops of dramatically after 6 months to 1% inflation.

So while nobody is looking ( or rather, while everyone sees it as a pump and dump) they accumulate milions of coins using a network of CPUs. Actually, they want you to believe it is CPUs, however the Quark algorithm is easily translatable to GPU. After all, it is almost like running SHA-256 7 times in sequence.

So the insiders have a GPU farm, while the masses are karnking away with CPU.

IMHO, people playing Quark are being gamed big time!

This is exactly what I've been hearing. Like always, thanks for the technical explanation.

Algorithms that don't use memory like SHA-256 ( Quark is just a variation of this ) can easily encoded to work with GPUs. Scrypt uses memory but does not use a lot, so it still is efficient with GPUs. Scrypt_Jane based algos vary with the amount of memory, the Yacoin variant can use GPUs but not with the kind of speed up as Litecoin's scrupt.

There are memory hard implementations that make GPUs difficult to work with (see memcoin, electreum) these are truly CPU bound and can't easily be gamedby GPUs. Primecoin is a CPU bound coin, because the multiprecision operators it requires aren't very efficient on GPUs. Primecoin however if flawed because it can't raise its difficulty beyond a limit.

Stuff like NXT and MSC aren't really coins because you can't mine them. So they are kind of like stocks that are strangely enough issued by annonymous people living in Russia (in the case of NXT).
