No one invests in Shitcoin, everyone trades with Shitcoin. DCA is not a useful method for trading. DCA brings to mind long-term Bitcoin investment, as Bitcoin is the only coin that is reliable for investment. You can't call Shitcoin reliable for investment. Because Shitcoins have less ability to recover value and cannot pump up the value like Bitcoin, many times Shitcoins are lost. No sane person would ever invest long term in such coins. Many trade with Shitcoins, I would advise them to be careful because trading in Shitcoins is also very risky. We know Bitcoin as investment and DCA as investment. In all types of investments we should be long term especially in DCA without long term you will not get good output.
Exactly, that's right mate you can call shitcoins investment and is not encouraging to use DCAing method on shitcoins because you may only endup increasing the chances of getting reckt. So the best investment that suit yhe DCAing method is bitcoin, is more reliable compare to other coins. Like you say shitcoins is only meant for trading not holding, and to trade them is also kinda risky because of their high volatility, and most of them might be a pump and dump project.
Shitcoins are not worthy for investment and it will be so impulsive to consider shitcoins for investment and using the DCA method, it is just a total waste of money.

DCA method is use for bitcoin because it is reliable and safe to invest bitcoin. Investing shitcoin is very risky and it is not a good investment decision, bitcoin is more reliable for investment and if one is able to exhibit patience to hodl it is an investment with good result.
