I haven't really mastered it yet. I am still a novice here lol. But at least I know the basics. I got to watch some videos on cryptocurrency on stormgain. They were helpful. I used easy wallets for a start that are easier to maneuver. But at least I have past he threshold levels now
I don't really think he's asking if you have mastered cryptocurrency but how do you come to know about its existence and what they are all about and how to invest in it.
