Since 2014 until now I have noticed that bitcoin and the crypto industry has grown very rapidly where currently its market capitalization is a testament to the successful growth of this industry.
I have been here and around people who support this growing industry such as traders, investors and bounty hunters and others. One fact about these people is that 90% (maybe more) of the people I know who support this industry are not formal workers who usually work as government employees, but they are non-formal workers working part time in some real businesses. There are only 2-3 out of 20 people (not the actual number) who are formal workers as government employees who are currently still trading crypto at my place to this day while the others are non-formal workers. What about those you know in your country, does this happen in your country and the people you know? I don't think there are any restriction governing formal workers involved in this industry as investors or traders.
In my country there are still few crypto users, but from the local forums that I follow, many who work in cryptocurrencies are mostly not formal workers like you mean, facts like that of course are almost the same in any country because when someone is busy with formal work, they will not have time for cryptocurrencies and cryptocurrencies of course need special skills, especially knowledge about investments such as trading.
Formal workers do spend time working in the office for 8 hours, especially if the office is far from where they live, time is up on the trip, be a formal
workers until the house is tired. Meanwhile, on weekends, formal workers spend time with friends or family, then they will have no time to
learn cryptocurrency. I agree with you, it seems like all countries will be like that. So it is not surprising that the majority of crypto investors are not
formal workers. Especially in a country that is a third world country whose economy is still bad, there are still many people who can't afford to pay
internet bills. So they can't get any information regarding crypto, whereas people who can access the internet more easily get opportunities to earn
income. This is one of the reasons why in the world there are still many people who do not know Bitcoin, because most people do not have time to
find information about Bitcoin.
