Investing is Widespread now in the Society such that the Inability of not Investing, is Paving a room for not Benefitting from the Outcome.
And Right now Investing in Crypto is a yardstick of measurement and has created an opportunity that's reliable and trusted..
But I really can't tell how thus Investing in The Economy will help one's Country.
For countries that the government is not cryptocurrency friendly I don't see how the use of "investing in crypto", fits in as a yardstick of measurement in such country's economy. Perhaps few citizens might be involved into cryptocurrency trading and investing but nocturnally.
However there are many ways investment could add value to a country's economy but that actually depends on what you are investing into.
For example; investment into huge real estate (housing) company, such estate company ends up paying tax to the government and such tax is a benefit to the country.
