The real weak hands are those who fantasize about some imminent 10k bubble looking at retarded exp log chart trendlines and then dump when inevitably it becomes blatantly obvious that their inflated expectations were wrong.
Bitcoin will prove to be the best investment around, even today, with far far far lower growth rates than what people are expecting. It's fine to fantasize about these things, just don't dump if perfection doesn't occur. Oh, and these fantasies are not impossible. They're not certainties either of course.
I think that there are several in bitcoin who have similar situations to mine, in that they are playing long-term. They are betting on some kind of meaningful increase in BTC value in the coming years (possibly 10 to 50% per year), and they are hoping for the possibility of real great increases in value (possibly 100% to 1,000% per year), also they are prepared that BTC may decrease in value or remain flat, but consider that decrease in value scenario to be the least likely. So they are weighing the various possibilities.
Surely, NO ONE exactly fits the calculation model that I outlined above, and each of us likely place slightly differing probabilities on different outcomes, but I believe a large majority of long term bullish bitcoiners have some kind of calculation resembling what I outline above.
