Selling out of necessity is okay. But selling Bitcoin to replace to fiat without an urgent need is worth calling it weak.
In this context, we should be able to separate them as well.
Those so-called "weak hands" in my opinion are the ones who are easily influenced by opinions that demonize the future of Bitcoin because they personally have no knowledge of Bitcoin at all.
I'm starting to remember when in the old days there was a group of people who very often badmouthed Bitcoin and glorified the products and systems they followed. For example, a group of people who follow the GSC path are currently experiencing a scam until some of them eventually also enter into cryptocurrency trading and choose Bitcoin as the best asset.
They do not explore or find out clearly before deciding to join the community you call it. They are tempted by the profits that are obtained after they provide capital for trading so that when they see your active routine on this forum, it is considered useless. In cases like you describe, we can't blame them. They are just victims who don't want to learn.
