£1.5k to £17,000 in 2 days. Is this real?

I came across this video on tiktok, someone on trading212 had managed to 'turn' 1500 into 17k in literally 2 DAYS?! I'm not really clued on with technology/social media but I just wanted to post it here if someone else can find out how this is possible? It sounds too good to be true so far?

I did also decide to investigate and my son also checked and compared it with the chart and it all weirdly checks out...

The OP in the video literally did manage to somehow time it all correctly, and it looks like they made a killing on the CFD on Trading212. That's also not it, if you look at the previous posts they also caught a lot of other winners, which conveniently shot up 20-60% and some even more than 200%...

Curious to see what you all think? Is this a gold mine that I've just stumbled across or is it just another fake thing?

Another theory I have is that they some how change the stock prices and then benefit from it which I'm sure is illegal? Even if you do this, why would you post yourself on tiktok or show your face? It doesn't make any sense?
