What did you learn from the 2017 bull to bear transition? What advice would you give to a newbie?

Title. I got into crypto fairly recently, in March 2021. Having not experienced a bear market ever before, I’m really keen to hear what the transition was like and to learn about some of the lessons that it taught you.

Here’s my take on it as a newbie: there’s a huge run up, BTC peaks, a month later, Alts peak, and then the market dips 70% and we go into a bear.

I’d also like to know how did you handle your investments? Did you just go into stable coins, or did you get some BTC too? What would you recommend as far as selling your holdings?

I think me along with a lot of new people in the space would really benefit from this advice. Thanks!
