The link teaches nothing comprehensive or worth while about Bitcoin
Just his price history and I don't think that's what newbie should be checking out.
Like is usually recommended here, I would recommend mastering Bitcoin by Andreas M. Antonopoulos.
It did help me in understanding most basic terms and the forum helped with finishing touches and improvement.
Mastering bitcoin is good for people if they want to know some technical information about bitcoin like how seed phrase is generated and how addresses are generated. Also if they want to know about bitcoin networks and nodes. It is very useful for people that read it.
But what the OP posted is good for newbies to know bitcoin price history. It can let news learn and know when to invest and when not to invest in bitcoin.
