It's perfectly possible, respectable individuals like the Xapo founder believe it so as well:

"In a video interview with the Wall Street Journal, Mr. Casares says he’s not worried about bitcoin’s own volatility hampering its adoption – though he expects significant volatility over the next few years. He predicts that in a decade, one bitcoin will be worth somewhere between half a million dollars to one million dollars."

Of course, the dumb ass average Joes that cannot think outside the box and consider any prediction like that as insane, will never make it. They will always find excuses "Oh he's heavily invested, oh this Bitcoin thing will crash". It's what they want to believe so they don't have the risk of buying and holding, and the ones that already have coins will not be able to resist the urge to sell when we are back to 1K or so. The people that is going to make it big within the next decade are only the 1%, which is what makes such a big price possible, because there will be a massive redistribution of Bitcoins in each bubble-burst cycle.

you can see the best answer is to play the signature campaign and now all rank can play a sig camp from rank newbie to the legend.
you can search for additional in section https://bitcointalk.org/index.php?board=71.0 , this is what I normally do to get bitcoin

300 would be nice, I still think BTC is under valued at its current price, imo it should be 450 USD per coin. I don't think that's being unfair. I'm unsure if we'll reach 300 this month but I certainly hope so.
I'm still hoping to hear some progress from the Winkles on Gemini, I expect progress on that soon & we could get a significant pump on that news.

Head and shoulders forming? Please, bulls
