No need for obsession with "anti-custodial". Custodial wallets in a certain amount level are just OK. This is just a game, to incentive and help kids to get into Bitcoin, is NOT their life savings.
People should start thinking like a bank and use the 3 levels of stashing BTC:
  • HODL = most of your savings, not moving them, only in special occasions when is really need it
  • Cache = where you manage all your inbound and outbound, organizing by category, coin control, coinjoin, node etc
  • Spending = mobile LN wallets, custodials with small amount, just enough to spend quick.
