Pretty much the only thing anyone needs to understand about Bitcoin is that it's a very high risk "investment". It's also pretty useless as a currency (crypto or otherwise) compared to some of the alternatives.
Yes, there have been many people who have made a huge amount of money through Bitcoin, but those thinking they can jump on-board today and replicate their success are kidding themselves.
Now, I don't pretend to be an expert when it comes to finance, stock markets or trading crypto, but some fundamental issues scream at me not to touch Bitcoin with a bargepole. Pretty much the only reason Bitcoin has increased in popularity this year is due to hype created by the media. That is not a good enough reason to pour money into Bitcoin or its derivatives.
