The answer is very easy to how could you learn it. Cryptocurrency is the easy way to become rich if you get yourself employed in it. Cryptocurrency is the exchange of digital currency to generate profit.
You need to aware either that crypto currency can make someone goes bankrupt just a few times. Yeah, I read a new on this day that there is a bitcoin investor who just liquidated and he loses $4.8 million on bitmex. Could you mind thinking about it?
There are many people that before they start cryptocurrency they didn't believe they can be rich from cryptocurrency until they learn about how a friend become rich with cryptocurrency.
There is no instant way to become rich especially in crypto currency, you may need a lot of effort even you have to spend a lot of money to buy bitcoin or some altcoin and holding them for an unspecified time. But, I doubt if there is someone who just buys crypto currency and he just gets it from recommendation, he didn't know crypto currency before he just knows that cryptocurrency can make him rich quickly. And that is the wrong way, spending money to invest in crypto currency need a lot of time, I mean you have to spend about crypto currency first and make your own portfolio and this need a long time.
