Moreover, this can at least reduce the unemployment rate in a country because the younger generation can generate their own income from various means through cryptocurrency.
Cryptocurrency is not so much about generating sources of income or generating employment, you know. It has more to do with the decentralized transmition of wealth or value. When comes to developing countries, the youth still needs to find sources of income which are closer to the traditional ways to make money, an actual job.
Speculation and investment in the long term can help to increase the value of one's portfolio, that is true, but a whole generation of people cannot rely their destiny on the cryptocurrency market.
The decentralized transmisiom of value which is enabled by Bitcoin and other cryptocurrencies has had a very positive impact in developing countries, that is true. Since they allow to avoid the full consequences of inflation and the reckless economical measures which could be taken by central banks, leading to the decrease of value of FIAT.
Just keep in mind one entire nation and population cannot depend on crypto, it is supposed to be a secondary market to what the country actually does for a living, being tourism, extraction of oil or exportation of tea and vegetables.
