&gt;The author is ignoring the fact that there are no refunds with bitcoin.<p>The author&#x27;s first point was that &quot;the unbanked want to remain anonymous&quot;. Refunds cannot happen while being anonymous.<p>Bitcoin is a replacement for cash, not an pseudo escrow service which we have come to expect in the western world with credit cards. Transactions are built on end-user trust. Credit card companies introduce a third party into the transaction which costs money. This is not a bug of bitcoin, it&#x27;s a feature. The services you are referring to can, however, be built on top of the bitcoin system.
