Already this might have discussed. The growth of bitcoin as well other digital currencies keeps progressing with time. By the time common people too have begun to use cryptocurrencies on their daily life. Compared to the fiat usage, common people using cryptocurrencies were low. When the usage increases what will be the preference of common people. Whether it gets used as investment, gambling asset, trading asset, alternate payment, darkweb usage source.
If its going to be used by common people, the best way is to use it as a medium of exchange and that is when the usage will be on the high side. Other than that, its not achievable and the reason is that the option of investment is a faulty because a lot of people are risk averse and unless returns can be guaranteed, this is not an option to consider. The same thing applies to trading. Gambling on the other hand comes with its own detriment which is the default attitude a lot of people have towards the activity. So the suggestion is all efforts should be geared towards the use of bitcoin for daily activities as that is what can move the penetration deeper.
