That's true but we need to teach them they won't need any bank account/custodian in the future. It's the easiest way but after that when they understand pros and cons they need to move into self-custody.

Ideally do everything without KYC but I don't know if you can use custodians like WoS or Bitlifi without "KYC" (it's nothing like scanning identity cards but they have your email, phone number...).
