Storm is over, but did we learn something?

What a nice morning this is, today I wake and everything is normal again.
The storm is over guys, hope you didn`t sell your coins
It`s all green again
But what lesson we learned from this guys?
What are your thoughts, how this black(red) Fridays changed crypto world or it all the same?
