I've been a student of Economics for some time now. Not in an academic setting by the way. But I have undertaken studies of Economics individually. In this time, I have never seen a case where hoarding any product has worked for good. It always end up more like a lose-lose situation. And this is a strategy only amateurs engage. I totally agree with the poster. The only way to improve Bitcoin prices is to create awareness to induce the public's interest. In other words, only increased demand ever benefits a particular market.
Of course, the net accumulation of virtually all the bitcoins will lead to nothing good. Bitcoin must first of all work as a payment system, as it was conceived. If the situation continues in the same way, it can very badly end for bitcoin: it will grow in price until one day completely collapses in price.
