For onboarding I use Wallet of Satoshi. I know it’s custodial. But you don’t want to kill people’s interest explaining channels, inbound liquidity and stuff. You need to show that “it works!”
On #BTC Prague I even onboarded KuCoin representative who was 100% shitcoins to #Bitcoin. He had problems paying for his beer and we got even via WoS. He was amazed and promised that he will look more into Bitcoin because until now he doesn’t know BTC can be THAT effective.
