I personally believe that period close to halving is the best fucking buying opportunity for the upcoming years.

If by "close to halving" you mean 1-2 years prior, then yes.
"Time IN the market beats timing the market."Exactly. I believe that and I am no longer waiting for BTC to hit my stupid trend lines.
My perspective has changed a lot while learning more and more about the current market situation and I think, we will surely touch the realized price (I made a post above) before making any new ATH and that would be, the best fucking buying opportunity one can have.
I do also see from the realized market cap chart
that you provided (and linked the source) above, the current BTC price seems to be quite a bit above the realized market cap, and at the same time, you can see from the chart, that there are extended periods of time in which the BTC price does not go into the green shaded accumulation phase, so it just seems weird that anyone would really anticipate that the BTC price is actually going to meet the realized market cap in the near future.
In other words, we could have another year or two of the BTC price staying higher than the realized market cap without the two touching in terms of down before up.
For sure, I am not suggesting that there are any guarantees because even with various charts, we cannot really assign any level of confidence that some kind of down before UP is not yet going to happen.. because down before up, or the accumulation green phase that is shown in the chart could actually end up happening at any time, even if it is not equally aligned in terms of places in which such accumulation phases had happened previously.
