In the end, the answer to the question "where the price of bitcoins comes from" and why it is worth so much, you can say that it is ultimately worth as much as people buy and sell it. This is often just as much a matter of human psychology as economic calculation. Do not let emotions dictate your actions on the market; this is best achieved by defining and sticking to the strategy. If your goal is to collect Bitcoin, it is a good idea to set a fixed amount every month to buy bitcoins, regardless of the price. Over time, this strategy (known as dollar cost averaging) will allow you to accumulate bitcoins at a decent average price, without the stress associated with attempts to predict sometimes wild fluctuations in the price of Bitcoin.
