I agree with you that it is most effective to continue investing in Bitcoin using the DCA strategy. Bitcoin has proven itself in terms of trust, technology, and economics compared to other coins. The long-term survival of shitcoins or meme coins is uncertain. Bitcoin is a decentralized digital currency. Bitcoin has shown the ability to survive in the long term. If we want to run a DCA strategy, we need to do it on an asset that has a future and Bitcoin is the best in that regard.
Don't be fooled by the Alts, you must realize that BTC is the King, without BTC the others would not exist, if you want to obtain a good financial system for your future you must have and accumulate all the BTC you can, it is good to always set aside some money and buy BTC Whenever you can, if you have a weekly or monthly plan it is your decision, but it is better that you always make a plan.
