I observe this market for three years now (however started trading only few months ago). What I got from my observations - I think fiat economy schemes aren't applied here. Yes, we see huge pumps once in a while, but usually prices during pump predict the future prices (it may happen much later, but eventually the floor will reach this level). I'm not talking about scumcoins here, which are getting pumped only to be dumped afterwards and abandoned by developers after they made some profit of it. But decent coins usually don't drop that significantly (maybe in 2013, but at the end of the day market reached, and overgrown even that level).
