What do you think will happen tomorrow with the BTC (up or down?) if the stock markets worldwide crash again?
I am afraid that the BTC will then go towards 3k or even less. The altcoins will hit it even harder.
I dont know what i should do today, sell all my altcoins?
There is high chance that things will happen as you say but what if it doesn't ? You can lose out of you sell all your coins and market failed to crash, it's your coins and you are the only one who can make decision here, I honestly don't let this market bother me, I leave my coins in my wallet
