I am very sad about this fact when people are engaged in science, but they are simply not needed by anyone within a country.
Money is needed for trading, not every country student can afford to allocate even $ 100 (scholarship of $ 50 per month), not to mention some more serious amounts that cryptotrading requires, not to mention the stock market, treasury bonds and stocks of banks.
Who says to you that people in science are not needed?
I'm surprised though because the current world revolves around science unlike in the time past when it was majorly about philosophy.
Technology is science of course and blockchain is from technology. Look deeper into yourself if you are in the science field and grow in it, you are needed.
However, for traders too, you can learn that or become a stock broker because the world has changed to be recognizing different kinds of exchange through trading, from crude oil, commodities, fiat currency etc.
