I can't imagine experience the bearish market of 2018 and yet not learning some very important lessons. I am sure a lot of people who in one way or the other were affected, will have something to say and would have known about how to engage of combat some difficulties inherent in crypto space.
The experience is not enough for one to quit, but it is mean to equip you more.
Those who are in crypto since last year are well aware how bear market works and how to keep yourself safe in bear market. Bull market is easy to survive as you most of the time get profits as coins keep on pumping but the experience gained during bear market will really help us in this year and we can better understand how to gain profit.
