Yes, of course the best strategy is a self-developed strategy supported by analysis as well.
In fact I must say that no financial advice can be considered 100% safe to be adopted by any trader even if it comes from an experienced user. I wouldn't suggest they follow someone else's strategy without knowing how the market works. I agree that they have to study, understand the correct strategy and apply it in trading.
some people want a shortcut in this trading market because that's what they after, they are thinking that they can easily gain profit without any studying or knowledge at first. this is why they are asking what's the best strategy. so they want to apply immediately and hope to gain fast.
if you want a very solid foundation when it comes to trading, you will patiently learn the basics, read and apply in actual trading. start small, this is not a race. you need to equip yourself with better judgment and that will come from years of experience.
