How to take profit?

Seriously, I think this is the hardest thing with crypto, the greed.

Do you have a strategy for that? Do you DCA out? Or just decide on an exit price?

I've never taken profits, and always regret it afterwards.

Currently, my dilemma is about Loopring, since the news are big but dumps always happen eventually, especially when it's not BTC or Ethereum.

How do you do that? That's the hardest part of crypto in my opinion.

Obviously the fear is to take profit and regret later.

You can't know for sure, but there has to be some middle ground?
