Regardless of when the bull run starts it really doesn't matter. Because this also includes speculation, according to the 4 year circle, after the halving it is the initial phase of the bull run. Regarding this, purchases can also be made at any time, because a person's economic situation will definitely be different. The point is how strong we can hold and be patient to wait for the bullrun to occur.
Yes, the next cycle should start in 2024 after the halving, so now, when many coins are at the bottom, is a good opportunity to buy bags. And I agree that it doesn't matter how long you have to wait for the bull run. The important thing is to remember to buy as much as possible.
The bull period also usually lasts 1-2 years after the halving. If the halving occurs in 2024, the bull period could last until the end of 2025. This is according to the history of previous bull runs. When choosing a coin investment, you also need to be careful, because not all coins will experience an increase in price. Plus there will be many coins and scam projects that will emerge in the bullish season, so if we carelessly invest funds there will be a chance of losing.
From history we have seen the same bull over the years, whether for the next year the bull could be in the same position as the previous position the bull came in after the Bitcoin halving after 1, 2 years later or it will change. Elite investors always try to find loopholes in Bitcoin investment by various ways to change processes that don't want to be the same as history, suddenly small investors like me don't meet expectations.
