I am following a shopify/dropshipping method and my niche is keychains, trinkets, plushies, anime/movie/show related products that fans will buy. Low cost/easy spending on impulse type of things. Target market is 12~30 year olds, who like cute/trendy/random crap. I FEEL like this is a saturated market... Am I overthinking? I get this feeling because on AliExpress these things are selling in high amounts.
