Useful video for cryptocurrency beginners

A video from an experienced trader in which he shares the lessons he's learned and how he would do things differently.
My favorite part of this video is the advice to divide you initial investment into 10 parts and put each part on a different coin (7:14 in).

Please share the videos that explained things to you in way you could understand. What one or two specific things did you learn/remember from the video?
This is from Cryptocurrency Market channel on Youtube.
