UGMA and UTMA Accounts Comparison use for Forex?

Can someone please explain to me why someone case use a UGMA and or UTMA with stocks/bonds/etc… but unable to use this with forex?

I’m just literally confused why someone cannot use the UGMA/UTMA with forex.

Is anyone able to explain this to me? (It seems not able to make sense how I am looking at the information and requirements)

Because all forex companies I know about keeps saying that NFA requires everyone to be 18 years old.

Yet, children are able to trade stocks/etc… and not be 18 years old?

Someone clarify this please?

I’d love a good explanation.

actual answer, not well it’s dumb but that’s the way it is

And if the dumb answer is the only possible, how hard is it to FIX IT versus ignore it?

Thanks in advance…
