What lesson did you learn from the market this week?
I personally, learnt to always take profit.
Take profit? or take out your coins from centralized exchanges because you don't know when they are going to collapse like FTX.
So create a wallet that you have total control of, have the keys, and save it. Others will say that just leave enough in an exchange for your trading, for me if I have more than $100 then I will withdraw it immediately just in case.
And for investments, just be careful on shitcoins and meme coins as they could be devalued or lost their worth very quick.
