Why is taking profits so hard but putting money into crypto so damn easy!

I have been putting more and more money into crypto for years now, yet i havent cashed out a single time. Everytime my portfolio is at An ATH the greed takes over and i want more and more and in the end IT all drops 50% and i wish i sold some. Yet i make the same mistakes over and over again. For me, taking profits is Just too hard. The feeling of missing out on big money is to big for some reason. But putting money into crypto at any time seems like a good idea in my head. Damn i need to get a strategy next run!
