Well this or just chance. Lot of Youtube videos about the next amazing 100x coin late last year.
Like everywhere in the world, here too there are scammers too, from false advertising to hacks and so on.
You have to understand what makes a good project before falling for all "100x" ads.
I completely agree with the knowledge though and it is hard to grasp the basics etc.
There are a lot of layers of "basics" depending on what you want to achieve, from how to safely store and access your coins and tokens to internals how they work.
Each extra layer makes you more informed for the decisions you will make.
That being said, if you buy mid 2017 with no understand of anything you could have made a lot of money so there is an element of chance but mainly it is hard work I agree.
Cryptocurrencies are not a "get rich quick" scheme. If you want to invest, you better research, like for any kind of investment.
If you invest in a couple of good projects, some of them may give you great returns. If you just invest randomly you have a good chance all your investments will turn bad. In investment field math beats chance.
