I&#x27;m not sure what Bitcoin equivalent of &quot;leaving cash on the street&quot; you&#x27;re inferring. It might be helpful if you elaborated on that.<p>Bitcoin&#x27;s non-physical nature (as compared to paper and coin currencies), I think, makes it more of a metaphor to a bank account or debit&#x2F;credit card than a currency. This likely is a UX flaw, as you state, but it&#x27;s a pretty big flaw.<p>And credit cards, in most jurisdictions, have lots of protections against theft and fraud, as well as consumer protections like chargebacks and transactions are reversible, of course.
