Dave owes John $10. John would like to be paid in bitcoin.
Dave signs up for CashApp, provides ID, uses his bank account to on ramp and purchase bitcoin. John provides Dave a self-custody bitcoin wallet address and bam! John received bitcoin from Dave, straight from CashApp.
Dave decides he's into bitcoin and decides to buy $100 and self custody, withdraws coin to his self-custody wallet address.
Dave owes Jenny $20, and convinced her to accept bitcoin. Dave pays Jenny $20 from CashApp directly.
Dave has "withdrawn" from CashApp once to his own address and "sent" to 2 other addresses (John and Jenny).
In this scenario, which wallet identity can be doxxed, beyond a shadow of a doubt? Would your decision on who's doxxed hold up in court?
