Nayoung, you must be in a tough situation. I'll answer the question like this. It's a positive sign that many people sell products are marketable, and even if you benchmark a lot, if the marketing routes you sell are different, you'll become competitive again. You don't have to worry too much because you'll know everything once you try! In fact, the most difficult thing is that you can't register after thinking about the first product! Whatever it is, I think you should upload the first product!
