However, not everyone is in a hurry to spend their savings in this way, which are stored in the form of a digital currency. Most owners of bitcoins who buy coins from miners, deep down hope that the rate will rise unexpectedly and there will be an opportunity to sell crypto currency profitably. This is one way how to earn with bitcoins.
Most people are still ignorant about bitcoin and how it works. It's adoption will take a while otherwise this bitcoin/crypto trading you are talking about has been a round for sometime in form of Forex trading in fiat currencies digitally.
In this case we trade currencies in digital form too so I don't understand why you would say that people fear storing their money in digital form.
