In a resource like this it would be great to have a section on the generalised style of traders and rule of thumbs for each style so newbies can get a head start.
eg. Passive investment - buy and hodl | Active investment - day trading - TA or buying and selling on rumours and news

Also, a basic understanding of market caps and how they are calculated by the demand/ supply and even touching on herd behaviour when markets increase and decrease.
eg. if the market cap drops by $100 billion it doesn't mean $100 billion was converted from cryptos to fiat.
