Of course bitcoin can help improve the economy of a country, because I've seen a lot in this community they've made bitcoin as an income and even a full-time job for them. Indirectly they have helped improve the economy of the country even someone unemployed has a good income from bitcoin, for them the reason is only one because of the very high bitcoin prices that make their income from bitcoin for the better.
The fact that people make money on the Internet does not help the economic development of the country. Moreover, these amounts are not taxable and therefore they have a negative impact on the economy. It is for this reason the governments of all countries are grappling with a turnover of bitcoins.
