HODLing sounds simple, but I really don't buy the "just set it and forget it" advice. You still have to keep your coins safe, manage your risk, and figure out what you'll do when things shift.
Holding is the easy part. Sitting through the actual ups and downs of a full market cycle is what really tests you.
You should determine what your strategy is to accumulate Bitcoin regularly, from the cycle of market ups and downs. Holding is not easy, but it is not too difficult if you have discretionary income. If you have the funds available, holding Bitcoin will keep your funds safe from inflation. The phrase "hold and forget" means to hold Bitcoin for the long term. You are advised to forget so that you do not sell your holdings during the pumping.
Basically, everyone's financial situation is different, and therefore it is not realistic for everyone to adopt the same strategy. But yes, if someone wants to get a good chance of success from Bitcoin, then they must hold it for the long term, and to hold it, you must stay away from overthinking the main thing.
When the price starts falling rapidly, many people think that it will fall further and they sell out of fear, and when the price starts rising rapidly, they sell too quickly in the greed of profit, this kind of thing can never be done. Being consistent in your plan is the main thing, and this consistency is very important as an investor. You have to be careful in controlling emotions, controlling greed, and you have to be stable towards your goals. And for this, it is important to be careful about your financial capacity and invest within your capacity. No matter how exciting or scary the market is, you have to be stable towards your long-term goals.
