Well I think your idea is excellent, I have basically always said one thing, when you have the opportunity to buy BTC with DCA it is an excellent method, because everything is adding and adding, especially when the price drops and if your plan is until 2029, it is a very intelligent plan, the more you accumulate the more money for the future, I believe that in 2025 the price of Bitcoin can grow a lot, it may reach $100k and pass it, but of course we have to wait to see how things are handled, because in the world there is a political scheme that basically speculative markets can be affected, as well as other fundamentals.
Now only if we are investing in bitcoins with DCA method then we only need to aim to invest in bitcoins. So if you invest in Bitcoin at a high price and in a short period of time and immediately sell your holdings when the price of Bitcoin rises then the DCA method will not work. To invest according to the DCA method, the investment must be long-term and the thought of holding bitcoins only, and if you are holding bitcoins with money at any price, then keeping it for a long time will give you the maximum profit and your money will be together. Your investment may be approximately 5 years to 10 years or more depending on your strategy and mindset.
Now usually the Bitcoin DCA method is that it has survived in the market with reliability for a long time. That is why all investors invest in Bitcoin. Investing in Bitcoin is likely to be the most profitable, as Bitcoin prices have only increased over the past 14 years. If you notice the market value it is around 57k dollars at the current price, but mostly bitcoin acceptance and it's popularity all over the world. But anyway Bitcoin is Bitcoin because Bitcoin is the only hope in this cryptocurrency that the probability of loss is very low when investing.
