Getting emotionally attached to money or an investment is a wrong move and shouldn't be encourage with the whole "Holding scheme". As investors,  we're to see every investment we participate in as a vehicle, leading us to our final destination (financial freedom).  Every investor should have a plan (strategy) and when you hit (reach) that target follow your plan (if it involves cashing out do that). Don't get emotional attached.
Just an advice: if you notice you're getting emotionally attached to an investment whether it be Crypto, stock or whatever, it is safer to cash out immediately to take some break or just move on to something else you're not emotionally attached to.
