Me personally, it depends on the product you are holding. There are some things I just flip for profit regardless of what the coin or token use is. If I think it has long term value, I still may sell a small % to recoup my original investment cost (and maybe some quick profit) and hold the rest long term. I think it truly varies on what you financial goals are, what your immediate financial needs are, and what your long-term plan for savings/investments are. It's a true balancing act. Sometimes you need to sell for capital into another great opportunity. In the crypto space there is such a thing as holding too long. Only certain products have true long term value.
