Can you predict how high it will go before crashing again?
No and you shouldn't try.
Will you sell at 5000, then watch it going to 50000 and not buy back at 10000 or 20000?
It makes no sense to sell at a specific price if it bubbles up making new ATHs.
It makes more sense to wait for a confirmation that the bull market peak is in and price structure is shifting. Waiting for confirmation instead of simply trying to call a top. If you try to sell as it's going up like this chances are you are going to be left behind and miss the real bubble/pump.
It's the same thing at any bubble cycle.
