Excellent point Digitalindustry! Anyone who wants to sell at any point - go right ahead. I have every confidence that there will be someone there more than happy to buy them - and then some! Plenty of BTC has exchanged owners during its rise - Quark will be the same. In the future, there will be people regretting selling at 10 cents, others at $1, who knows. IMHO, the majority of good alt coins will be going up (a lot) in the months and years ahead.
Personally, I'm betting big on Quark, eMunie, Peercoin and Devcoin.
1. the principal by which it exists is flawed - its a centralized "group" that issues Devcoin to people ?
2. it's SHA256.
Peercoin is a first of doing what it does , but PoS is very innovative - but ultimately its something that one would have to get very correct i think , its a powerful driver of influence, of the currency direction - this way or that way -
