Jorge: "Nobody who has heard of Bitcoin and holds USD thinks it is worth more than $250".
Me: "Wrong. Someone might value it at $300, but still refrain from buying the amount he wants to buy now, because he expects to be able to get a better price by spreading out his bids".
(Similarly for someone who buys btc *above* his own valuation, because he plans to sell them off after the "pump" he created himself.)
I would rather say "Nobody who has USD to invest is willing to pay
$250 260$ for 1 BTC". On a high enough level of analysis, the reason doesn't matter. It may be that the guy has never heard of bitcoin.
I concede your point about strategic non-buying, on a more detailed scale of analysis. However (as you remarked) that does not contradict the rephrased statement above: the trader who waits for lower prices too thinks that 260$ is too much to pay.
