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.
There are some stories are there who made 1000x overnight with shitcoin but it's like winning lottery so it happens
once in a blue moon. While bitcoin is almost guaranteed since it has proven record over the last 15 years or so while shitcoins have barely have record for months and 99% of them will be at zero after a couple of months. So my money will be safe when I go with something that is guarateed to be there in the long term instead of gambling with shitcoins and definitely it's not worth saving your hard earned money and investing them on shitcoin based on DCA.
The concept is simple, use only bitcoin to hold your portfolio value and might take chances with 5 or 10% of your capital with shitcoin is you have dream of winning that lottery but I won't do that which is my personal opinion which others might have differ with.
If you want to see yourself in the next 5 or ten years being better financial status than your current one then go with Bitcoin.
