This method will really be useless if those scam devs do their rug pull schemes that's why its better avoid doing shit stuff with those thing and just better focus on more realistic investment with Bitcoin.
Yes, the strategy can certainly be applicable to other assets if it can be applied to the appropriate resources. Dollar-Cost Averaging (DCA) is a suitable and excellent strategy, especially for assets like Bitcoin. It may also be applicable to other assets, provided they are not associated with scams and have the potential for future value appreciation. DCA can be a suitable or excellent strategy for any asset that is appreciating in value, as long as it is not involved in any fraudulent activities.
Particularly if you are planning to invest in shitcoins, I would like to warn you upfront. In shitcoin investments, you cannot rely on strategies to protect yourself from loss. Investing in shitcoins means your money is at risk, just like in gambling. Investing in shitcoins is akin to gambling, where entering means you are likely to lose money or have a higher chance of loss.
For investment, I would certainly recommend Bitcoin and advise a long-term approach. In this regard, the DCA strategy is the safest strategy for Bitcoin investments.
