There will be the standard several-weeks' time delay for that surge, though. Still, even discounting all of that, I think we're going up toward the ATH and within a week or two, then beyond. (Very very short-term fall is possible.)
It is all probabilities ofcourse, but I don't see anymore, how sales would overwhelm buys.
The story might be a final push for many who have just waited over the months and years.
Btw. the most interesting part IMO was that
despite a million percent gain, he only sold 20%. With the remaining 4000 bitcoins he is among the top 200 worldwide and why not - Norway is one of the remaining independent countries. Even the taxman was curious to make the regulations conform to bitcoin and not the other way round.
So many people say, "I made a few hundred dollars then sold 'em." It's just impatience, otherwise they would keep some. When they get into fiat mode all they can think is, "My precious moneyses..." and maybe thinking about what they could buy with that extra few hundred or few thousand, they say, "I got FREE MONEY and you're all just playing around with virtual tokens! So long suckers!!" and sell every last satoshi.
I was thinking also, instead of talking about wealth in terms of bitcoins, we could talk about it in terms of percent of the total Bitcoin economy, like 4000BTC is about 4000/12000000 = 0.03% of the Bitcoin economy, or maybe something like 0.03% of all purchasing power in the Bitcoin ecosystem. Of course there are lost coins and hoarding that effectively make this quite a bit higher, but still it's an objective measure: it's what percentage of the outstanding bitcoins you own.
For example, if the Winklevii own 1% of all BTC outstanding and Bitcoin takes over the world, their holdings would (if they held them all) command no less than 0.5% of all the purchasing power in the world (even based on 20 million coins outstanding by then), and probably more like several percent. Outlandish wealth.
