When you don't panic sell when the price goes down 40%
Yes the smart true believers sell their BTC and then buy it back lower, and have 40% more bitcoins as a result.
Yeah. Like EVERYONE doesn't try to apply that simple logic to the market. In the end EVERYONE isn't a winner.
There's also no level of skill when doing that. One can train a child to monitor graphs and buy on the low and sell high.
Unfortunately too many people play bitcoin as a casino. Waaaayyy too many gambling addicts and not enough innovators that deliver bitcoin products/services to the masses.
I hear way too many people quack about bitcoin being a 'currency.' Dumbfucks have no idea what they're talking about.
