Yeah, but what if you bought at 0.100 and it never went to 0.102, and now it is at 0.090? Fluctuating prices is what can make you lose money, too.
The trend is down as the difficulty rises, so most traders are going to lose money on trades. And since traders are paying more for the shares than they will mine, they won't make back their money through mining, either.
The result is that some people will make money when they buy these shares, but most people will lose money.
