Why would I want to make actual purchases when it's rallying like this? You'd almost always be better off holding instead...
If no one is actually using the coin for practical purposes, you've created a glorified Ponzi scheme. The minute that "better off holding" is no longer the most common opinion, the price of BTC will drop.
I dunno how long that will take: it took years for Enron to drop to zero for example. But I do not place much trust in the whims of stranger's opinions.
