Most often, growth began in the second half of October, it seems that this time there will be no exceptions. You are right that the period of accumulation of investments should fall on a bear market, and it may be a little late to start buying now, when the price is near ATH. I think that this will bring profit, but there is a possibility that you will not even be able to get x2 from your investments.
We are about half of October and so far Bitcoin performs good this month. It's up nearly 7% so far in October and compares 7% to median at 12.7% and average at 14.8% from previous October months, it's not too bad performance from Bitcoin.
It's good with profit for people who bought Bitcoin at start of October and hold it till today, and Bitcoin journey to complete this October is 2 more weeks, but they can look farther. To complete this market cycle and bull run, Bitcoin has many months ahead, more than only this October.
https://cryptorank.io/price/bitcoin/analyticsx2 from $67,000 is very good ending for this bull run but I am happy if it only hits $100,000 or even lower than that. From bottom about $16,000 to $100,000, it is more than x6 for profit, and people who bought at bottom in 2022 and hold it or who invested their money with DCA strategy, now have good profit too. Their average entry price with DCA won't be too much higher than $16,000.
