Bitcoin is more than a currency, bitcoin has risen to an asset for one's investment, because many people get big profits from current price spike. Demand for bitcoin is increasing, giving extra benefits to bitcoin owners who hold it.
This has a lot more to do with hedge funds who have gotten into Bitcoin than individual users. Institutional managers have far more ability to affect the price than regular folks, and over the past few years there have been numerous private funds that have been started to buy and hold Bitcoin on behalf of wealthy investors
Do you know any of these?
Apart from the Winklevii twins (who might in fact be managing someone else's money, not only their own), I have never heard of investment (hedge) funds involved or even interested in Bitcoin. It is obvious that they cannot officially (legally) invest the money of their clients in Bitcoin (at least, not in the US as it seems to be the case after the rejection of the Bitcoin ETF by the SEC) but, on the other hand, if they are doing that via some gray schemes, how do you in fact know that there are "numerous private funds" trying their hand at managing Bitcoin assets?
