Definitely the crypto and bitcoin community are eagerly waiting and anticipating the halving come next year 2023 with very high expectations in price hike which is always the outcome of the occurrence but I would say that this estimate calculated by OP as shown on the website is based on assumption because there is every tendency that it is not 100% accurate.
Op has already stated that the result is based on the blocks that will be mined in different minutes, for example, a minute to 11-minute timeframe, and he shared that the website will calculate accordingly, so how can you say this result is based on assumption? It is based on proper block data.
We are waiting for the halving eagerly because after the halving, a bull run will start, and we are going to make some money out of it. More money will be inflowing into BTC, and the overall market will pump. And the good thing is that if ETFs are approved, we can see the price will rise to a point we didn't even have predicted.
Most of the analyst predicted that BTC can reach 100,000 dollars but the funny thing is many people still waiting for the dip
