A bearish situation is the best time to increase your portfolio and earn more Bitcoin, you can invest in methods to start making profits in a sluggish market. The downward trend is unavoidable, it is necessary to be equipped with knowledge of technical analysis to help you get a chance to make a profit. There's nothing to stop you from buying 1 or 2 Bitcoins when the price is low, as long as you understand the basics of technical analysis.
Buying 1 Bitcoin at a time sounds a bit ambitious to me, you can do it slowly by taking advantage of the trend.
Someone who buys Bitcoin by taking advantage of the current downtrend is a very good thing, but it would be better if after buying Bitcoin, that person is willing to keep it for the long term instead of taking it into short term trades for small profits. Because usually people who buy Bitcoin with so much analysis are people who like to trade for short-term profits and that is not the nature of investors who often take long-term profits. Because investors prefer to hold for the long term as their investment options before taking the profits they want.
