Holding in crypto its not something bad at all, but know when to hold and what coin to hold. Some hold coins they are supposed to have sold while some sell good coins they would have hold. One will ask how to kmow which coin to sell and which coin to hold, you can know thiw by being conversant with the project communication medium, check islf there are line ups of developments incoming, check team activeness, check the project timeline of any major event. This will give you a clue of wether to hold or sell. And always take profit once you meet any of your target. Dont be greedy don't hold unnecessarily
But this is the problem is it not? If we all knew what to hold,,, then for sure we would do it. Back in 2017 99% of altcoins you held grew in value, and so this made a lot of people think they were smart geniuses in crypto trading.
But the reality was that people were lucky and had the right timing, that is all.
