By looking at the cycles of Bitcoin halving, we can easily know the halving benefits of Bitcoin holders. Anyone who has held Bitcoin for a long period of time has received the highest price at that time and Bitcoin holders could easily profit if they sold their holdings, and if they tried to hold for the long term instead of doing so, they could have profited. A Bitcoin holder gets that opportunity continuously and will continue to get it in the future as the halving of Bitcoin every four years helps to increase the price. Anyone who is a long-term Bitcoin holder will definitely get a chance to make profit. And the most true thing is that everyone who has worked as a Bitcoin holder has benefited.
With the previous 3 halvings, the market has gone up and bitcoin has increased thousands of percent after each halving, and I still hope history can repeat itself again. But to be fair, we have no guarantees that the cycle will repeat itself again, and the halving will still be a factor in bitcoin price increases. For now, we're still waiting for that to happen, but there's no guarantee so I don't think we should claim that just holding bitcoin after the halving will make everyone profitable.
I hope 4 year cycle repeats but I don't rule out the scenario that it probably won't happen because we saw bitcoin hit an ATH before the halving and that has never happened before. Things are gradually changing, so don't be too subjective.
But I agree with you that holding for long can help us profit because bitcoin demand is increasing over time even without halving.
