Did You really learned for your mistakes last bullrun?

Ive being investing in crypto since late 2020 si i'm a kinda a newby, Last bullrun (My first) i lost a ton of money in unrealized profits, i had huge gains from speculating on shitcoins but never sold any, and holded most to +95% drops and Lost a bunch of money more than 20k(Lots of money i'm my poor country), i even lost like 500usd to luna, thankfully most of my money was in hard assets (BTC,ETH) i know they dropped hard too but they Will bounce back.

Recently i sold all my allcoins and buyed Even more BTC/ETH i still hold like 5% of My Portfolio un Matic and other promising allcoins but i learned my lesson.

Things that i learn un my first bull-bear cycle.

1: Stick most of your portfolio to the OG coins (BTC and ETH)

1. TAKE PROFITS, DONT BE GREADY.. have price targets and sell DCA IN and DCA out

2. Never buy alts on a bearmarket

3. It's ok to buy alts on a bullrun but sell quick when you make profit (better to have little gains than no gains at all)

4. If you want to speculate with allcoins never more than 1-2% of your portfolio.

Obviously this is my own opinión, what did You learn this last bull-bear cycle?
