First of all, I would never believe a unverified information on tiktok. Also I won't take that kind of a chance when my fund is at risk.
Right! TikTok can not affect the market in any way. But there are people who scam novice traders by luring them by showcasing their fake lifestyle.
forex market is too vast to be affected by TikTok. It is not like the cryptocurrency market where a single tweet from Elon can create a huge movement in price. It's certainly tho a platform that can be used to scam by convincing it easy money and you can make big profit in short term.
Forex is significantly bigger than Tik Tok, so it doesn't have what it takes to mess up the Forex market, but sure, it could scam a few rookies who don't understand forex.
Tiiktok can never influence Forex in any way. Though there are many people on TikTok who lure newbies and scam them. It is just the hub of scammers.
