I think IF you believe that a better cryptocurrency can take over Bitcoin Peter has a good point about the inflation, but I don't believe that will ever happen because core functions as decentralisation, security, network effect and branding are way more important than fast transactions and fancy features. Especially since Bitcoin is now already succeeding to build fast transactions and fancy features into second layers. A better crypto will be simply be copy / pasted into a second layer of BTC and be superior immediately.
