Good tips for beginners. The part about not getting emotional is very important.

What I like to add to newcomers into the crypto market.

Dont be intensly focussed on the short term. Just research, put some money in the projects or currencies that you like. And just let it sit there for a while.

Think about the long term the at minimun 1 or 2 years. It will always calm your mind to look to the future instead of the dip of the moment.
