A long-term investment means holding for at least 4 to 10 years. If someone holds for less than 4 years, it is not an investment, but trading. A new investor should only invest with a holding plan for 4-10 years at any price, then it will be recognized as a long-term investment. The reason for the minimum 4 years here is to hold Bitcoin for at least 1 cycle continuously, but it is not that the investor will profit after one cycle, if he holds Bitcoin for 2-3 cycles continuously, then he is very likely (about 90% likely) to profit from his holding. Because the possibility of Bitcoin's success in the long term is very high. So this kind of short-term fluctuation is actually nothing to fear. If you keep investing at any price, and keep holding for the long term, then success is waiting for you.
I see bitcoin this period as trying to change the narrative of traders and gratify investors. Most traders have run into bankruptcy due to market irregularities. Hodl your bitcoin and you won't be at the risk of developing chest pain due to losses. Traders could make the whole earth as gain only to go broke the next moment. Invest in your future and your dream which is a world of crypto.
Its not trying to change the narrative, but rather this is the best thing to do since that timeline is actually the recommended thing to do for people to possibly see the result of all the efforts they made for long term accumulating of Bitcoin.
If they are in trading for sure that they won't last that long knowing how market changing so fast and provably that after short time period they got broke instead of getting profit from selling their Bitcoin in short time period. We see how this option nowadays especially if market is so volatile since we don't know what will be the next movement of Bitcoin. That's why people should not pick this choice if they are not mentally stable since they are bound losing if they can't control their emotion. This is the reason why Holding is better since we don't need to think about other things including this unfortunate scene when market collapsed and the one we are provably need to pay attention is to buy more Bitcoins and try to reach those years we target for our investments.
