Well lets see:
1 BTC - buying QRK, pretty much worthless now
1 BTC - buying NXT, not worth as much as before
1 BTC - buying EAC, pretty much worthless now
1 BTC - buying WDC, pretty much worthless now
1 BTC - buying MZC, pretty much worthless now
Calling losses like that a scam is something I've wondered about, as many here use the term rather loosely. Why do people tend to call unwise coin purchases a 'scam'? Is it looking for someone to blame?
Most likely. In the stock brokerage trade, complaints like that are called "sour grapes." You see that kind of hurt all the time in the penny-stock forums.
But...as the behavioural-finance experts have shown, buying low and selling high is profoundly "inhuman" and hard to pick up unless you're practically raised from childhood to do it. The people who master the skill (to the extent which anyone can) tend to become really cynical as a result.
That's life in the salt mines. So it's not all that hard to see where a complainer is coming from: buy low and sell high
is much harder than it looks.
The best thing to do is to get into a coin with a long-term future, hope for the best, and pitch in if you can. There were Bitcoin "bagholders" riding a 90% loss in the tail end of 2011...when Bitcoin was selling at $2. A rising tide bails out people who bought at the top of an interim bubble and have the faith to hold on.
The funny thing about Bitcoin is that some "Bitcoin millionaires" picked up their BTC on a lark in '09 and '10 and then forgot about Bitcoin completely. Strangely, forgetting about it means there's no temptation to sell early on in the bull wave to snap up a nice profit. If there's a journalist around here, the story of the "accidental millionaires" would make a great human-interest-type man-bites-dog item.
