I'm doing similar, no idea if there is any tax implications of that though down the road. Or just screw it

Strike is the only one I have linked to a bank acct and that will flow through me for the most part. I did look and cash app allows the user/kid to choose to do the KYC part and from there if they want to transfer it into USD they can. But I'm pretty sure I can give them access to the keys and allow them to buy with sats independently while maintaining my own channel into that wallet for monitoring / tracking. That sounds pretty good to me?

Ya the sats would be non kyc for them if they want to spend it right? Assuming years down the road there's a minimum tax exemption anyways
