Well, if the market decides that bitcoin is worth $6000(for a few years at least, I doubt it though), then I'm fine with it. A bit of stability is good in my book as it makes mechants probably want it more, as I assume one of the reasons some merchants don't accept BTC is because of the huge price volatility.

Well, there is no way the price stability could be determined by the Market unless manipulated.
If Bitcoin remains $6500 for ever imagine what will happen if $10,000 worth of land goes up by 50% in 5yrs while you have $10,000 worth of savings in Bitcoin for that 5yrs... The land will be worth 15,000 while your Bitcoin savings remains $10,000 (at $6500) ... meaning that Bitcoin has become inflationary instead of the deflationary currency it was meant to be.
So you won't be able to afford the land anymore. You will need extra $5000 in order to afford it.
Manipulators may decide to increase Bitcoin little by little to make Bitcoin artificially deflationary... Still doesn't take away the fact that bitcoin is being held down and not reflecting its true value.
