virtuality of a skill depends on how one has to master it, once a wise man said (thats being wise) "to be the master you have to slave yourself" ....investment is the most important skill if i have to be capitalist (but am a centrist politically but not today..) so all the steemitans, from all walks, if the cryptocurrency is gonna down on a folk, let there be.....investopedia, several trading accounts and some few followers on stock-tweets.
one has to learn how world macroeconomics works now that a post is worth a dime.... is scarramucci (not sure bout the spelling)on steemit?
