How to Start Disrupting Cryptocurrencies: “Mining” Is Money Transmission
&gt; All cryptocurrency assets, not just Bitcoin, are zero sum. So every dollar “made” in cryptocurrency was simply provided by someone else.<p>Can&#x27;t you say that about any other asset? If I sell my house for more than I paid for it, it&#x27;s zero sum since someone simply provided me that money. But that&#x27;s not how we determine value. It&#x27;s positive sum because the buyer attributes a value higher than he had paid for it, otherwise he wouldn&#x27;t have bought my home to begin with. You can say no one can reasonably &quot;value&quot; a crypto currency, but there&#x27;s 100+ billion dollars that says otherwise.<p>&gt; There is no silver bullet, but there are a lot of things that can throw sand in the gears, degrading Bitcoin and other systems into unusability.<p>Ironically, the author goes on to describe a way to attack the value of Bitcoin and presumably drive its price down (destroying value). So it doesn&#x27;t seem zero sum after all
