This strategy could be what another Bitcoiner might have practiced or is actually planning to do too, but I have been on this forum for a year and three months now, and I have not actually come across people talking relatively to this type of Bitcoin investment idea more often, probably because they think it's not worth it or because it's just nothing special.
This kind of discussion will come at the time of the peak and you may yet to witness that in the forum so you feel people are not aware of it. The strategy you shared was probably discussed in a few hundred threads in multiple boards of Bitcoin so it isn't really a special strategy but an effective one as you said if one who successfully pulls their moves at the right time which is market peaks and bottomed down.
If not many, I have seen at least two old members of this forum whose comments stated that they have been holding their bitcoin for more than 8–10 years now and have not sold any bitcoin from their holding. while, the price of bitcoin has been going up during every bull market and falling again during the bear market.
HODLing is what most of the early investors follow because they know that simply holding it is enough to bring returns that is not possible in any other kind of investment so why take the risk of buying/selling and then buying again at the next cycle.
