Just want a view on my wife’s investing

Hey,

My wife has seen a TikTok channel, Neil Invests, and has started using the Trading 212 platform he recommends . I imagine slot of people are thinking of doing similar with me the upcoming Vanguard charge.

. He obviously makes a cut from people signing up to it through his link but I wanted to get a measured view on what he’s recommending.

His recommendations so far are essentially a portfolio made up of S&P 500 but also there’s a bit of gold and Microsoft. Apparently the gold is to offset any inflation which affects stocks.

The way she understands it is if she puts in £50 a month she’ll have £90k in 30 years (I think that’s what she said). Ie £12k investment turning to £90k

Is this absolutely nuts?
