It's surprisingly hard to get cryptocurrency without a KYC check in the UK - bitcoin ATMs and suchlike are banned.

Far simpler, if you're a teen that wants to get around the block, to just have an older looking friend do the video selfie.

What stops anyone from just mining it? Cryptocurrency mining may or may not be profitable at any given time, but it doesn't matter that you're spending $7 to mine $5 worth of cryptocurrency if you're willing to pay the $7 to get the VPN.

Meh, perhaps now, but there is an easy pipeline of work (mostly menial, Turk type tasks) for crypto that runs right past KYC. Cash for crypto is also surprisingly easy to find, again bypassing most KYC.

I am not sure what will be easier.

Mullvad even let you send cash in an envelope in the post.

I'm not sure most kids would jump through this many hoops. I don't know what will happen in the future, but I'm having trouble foreseeing a future where a sizeable majority of kids have cryptocurrency wallets. They'll probably just find a friend who has a VPN from parents who don't care or who don't know what it's being used for.
