Well, r0ach was right in that Bitcoin, after a big fake-out drop, is rallying smartly: close to $520 as I write. And there definitely is a short-term drop in many alts that corresponds well to BTC's recent pump.
Prolonged and pronounced success is not possible while the network capacity remains inadequate of needs and due to loss of confidence in Bitcoin with mining amassed in one country. The spread between Bitcoin price on chinese and western exchanges suggests this is probably a set up by the chinese who also read charts and analytics and made this awaited rally a self-fulfilling prophecy to fill their pockets. Technically Bitcoin is a colossus with legs of clay.
