How Bitcoin becomes a real currency

I also think that Bitcoin cannot become the mainstream currency in its current state. Bitcoin has so many unexploited flaws. The fact that it is decentralized makes it completely unsuitable to act as a prime currency. It has no minimum valuation guarantee. If a lot of whales decide to dump Bitcoin, the public would suffer immensely. We know that Bitcoin make the illegal transactions quite easy. So the crimes would increase if it started acting as the main currency.

Because many people uses it in everday living, you can trade, uses in online transactions. most of all it cannot be faked compared to fiat money.

One of the points in this article says, Bitcoin is deflater by its nature since day one, which is true. Therefore it can not depreciate, also because people not only use it as payment but also hold it to gain value over time.
However some people do the same thing with fiat money they hold and save it to spend it later, and it inflates due to many OTHER economic factors, not because people like to spend it.
