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.
It would not be wrong to call trading a kind of scam. Very few people have profited from trading, many people have gone bankrupt from trading. There is a lot of risk in trading, but in the case of long-term investment, the risk is reduced by about 90%.
You now buy Bitcoin and later sell it for a profit, in this way you will be in profit for some time, but at the end of the day, if you average it, you will be in loss. One of my friends who trades, he makes profit for the first few days and after a few days, he loses everything. I will never advise anyone to trade. Always keep the goal of long-term investment in mind.
Long-term investment also requires some general knowledge and patience. You should keep the investment time limit for at least 4-8 years.
