If bitcoin didnt have market value before July 2010, what does this mean? How could people buy it if it didnt have any market value then other than p2p, otc, and mining?
It has a market value but not fixed, you can always know this by checking for what the market price is at each time you wish to know.
If I could also depict what you meant by market value for other aspects, which talks about it's utilities and applications on various aspects of the financial economy, bitcoin has all its takes to keep relevance as it's the solution to diverse centralized challenges in finance.
