Bitcoin rewards early adopters with cheap coins. I consider you an early adopter when the price per microBTC is < 1 USD.
I'm an idiot for selling my coins, you should almost never sell your coins. Also it's not really a stock, i don't treat other currencies as stock, and i have never in my life experienced such a gain as i've had with bitcoin, the value has gone up 6666,6 %.
For some reason, Bitcoin seems to be sort of stable for a period of time and then tends to go hyperbolic for some reason, i think this will happen again in the near future until it breaks through or slowly goes stable again. The network might even fail for a while because of its popularity. It's slowly sinking in what this specific crypto has to offer.
