it's not very difficult for Bitcoin to go from $25k to $30k.
Maybe it's not that difficult but we have seen what happened to bitcoin where even increasing the price to $29k seems difficult because there is a lot of pressure to stay at the bottom price. But if the time is right, the bitcoin price will definitely start to increase and reaching $30k or even $40k or $50k will not be difficult and may only take a moment.
Perhaps we shouldn't focus on the Bitcoin price movement right now, what should be considered is how well you're utilizing the opportunity by accumulating more, truly we no that Bitcoin is ranging within some levels, we shouldn't dwell on or trying to determine what the price of Bitcoin in the coming months will be because it can affect your psychology in times of accumulating were as you over invest believing your psychology that Bitcoin price will get to a certain price before some months as such making you invest more in other to accumulate huge before the months you believe that Bitcoin will get to a certain price reach, perhaps you could be affected financially if it doesn't get to the particular price, is obvious that Bitcoin price will spike soon as a result of the halving coming next year and could possibly surpassed the all-time high but nobody knows when is going to be, so we shouldn't allow emotions to cloud our accumulating psychology to invest aggressively there should always be back up plan.
You perhaps made a very good point as true Bitcoin enthusiasts should not really care about the low or the prevailing condition before they buy as they continue to increase their vault of Bitcoin. But on the other hand, we should rather be more professional than just be a blind investor. Fine, Bitcoin has the prospect to move higher and appreciate in value over time to surpass the current ATH and still give the hodler more return on their investments. Yet, it will not be so bad to earn more when you are more professional in your striking level. Also, based on your insinuation, DCA is a good option, after all, you will not miss out as you strike at different levels/prices, but as much as DCAing is good, you might want to use better approaches that will earn more for you or that will complement the DCAing since there are many approaches to investing in Bitcoin, it's wise to diversify.
What I advise in this regard is to study the market carefully and never buy when the price of Bitcoin is high regardless of your DCA approach. Take the recent event for example, Bitcoin hit almost $27,500 recently, and that was when I knew fresh trouble might start, and you can see what is happening now. Nonetheless, if you are conversant with Fibonacci retracement, you would know decisively in line with the price action that the coin was stopped by the 61.8% 1D Fibo level and a bearish price action below the line pointed to a bullish failure and an activation of a bearish short-term reversal. At this point, a good investor will know what is going on and wait until there is the same condition favouring the bullish trend before buying the coin again. This is wiser than just buying and DCAing without a good reason to back it up.
This was how I was able to know how to deal rightly with my Bitcoin purchase when a similar condition happened in August when Bitcoin moved higher and barely hit above $28,000. It was the same Fibo that played out so well to guide me as 1W Fibo level actually repelled the price of the coin downwards. It's good to make plans this way so that one will not be a blind buyer, and once you buy at a reasonable price, you tend to make more money. So, it's not only about DCAing but DCAing rightly with further guidance like this.
