So if N was only, say, 5%, and there&#xA;&gt; was a large enough population of users who were systematically trying to&#xA;&gt; defraud merchants, we&#39;d already be having worse security than magstripe&#xA;&gt; credit cards. EMV transactions have loss rates in the noise, so for&#xA;&gt; merchants who take those Bitcoin would be dramatically less secure.&#xA;&#xA;Just pedantry: 100% of credit card transactions _can_ be fradulantly charged &#xA;back but arent.  In fact, only 2% are ever attempted.&#xA;&#xA;If N was 5%, then only 5% of bitcoin transactions _could_ be fraudulantly &#xA;&#34;charged back&#34;; so then why wouldn&#39;t only 2% of those bitcoin transactions &#xA;be fraudulant too, just as in the CC case?&#xA;&#xA;The comparison would then be 2% chargebacks for credit cards, equivalent to &#xA;0.1% (5%*2%) for bitcoin.&#xA;&#xA;&#xA;Not that I think that makes anything else you say invalid.&#xA;&#xA;&#xA;&#xA;Andy&#xA;-- &#xA;Dr Andy Parkins&#xA;andyparkins at gmail.com</html></oembed>
