I thinking hodling requires many factors, first of all research the product and future plans, if product i shit and no new things from the project, then hodling will bring only disaster.
This is why holding great coins is bettet than being trap with a shitcoins. Hodlers have to endure all the market losses and even when the price hit a new all time high some people still choose to hold knowing that it will dump after hitting the peak. Hodlers really focus on their goals, and its a good one.
