There is a lot more talk of pumping than pumping. Perhaps among alt coins the market is still small enough for that, but the price is mostly a function of simple demand.  If you buy bitcoin then use bitcoin, it's real power is revealed. Utility is the most important thing about bitcoin. It is the cheapest, fastest, and safest way to pay anyone anywhere. It is not an investment vehicle of any kind and using it that way is extremely risky. A few people may have gotten quite rich early on, but that phase is over. IMO. Those that did make a lot of BTC worked hard on projects that advanced the bitcoin economy.
In 2011 the vibe here was totally different. It was about taking on the banks and spreading the word. Now it's a bunch of kids that want to know what computer buttons to push to get rich. Now everyone wants a loan or a handout, or to be let in on the secrets. Well, the secret is hard work. If you want a lot of bitcoin then start something of value, go hungry while it grows, later the earnings will flow.
