many people believe holding because currently holding can be a form of controlling assets, so I think with holding we do not fully sell low-priced sales. we can make sales waiting for high prices in the future ...
Sure, sometimes, during bull runs, it is always sensible to get out of the market without being greedy and look forward to buying lower. It has been like this for a while now, and this is one thing we all expect to take advantage of.
It is not even about the belief anymore, but has a lot to do with just doing so since we simply do not have much choice based on how volatile the market is and if you cannot trade, the best is to just hold on to whatever you have for the long term.
