‘Bitcoin cannot scale to serve global adoption’

A quick web search will tell you that Bitcoin processes fewer transactions per second than, say, Visa. This is because Bitcoin is a final settlement system, similar to the US Federal Reserve’s FedWire, serving a limited number of larger-value transactions. In contrast, Visa is a payments aggregator based on an underlying final settlement system, such as FedWire, serving a large number of lower-value transactions. Like FedWire, Bitcoin scales to commercial volumes via payment aggregators, whether the established providers like Visa, MasterCard or PayPal, or new second-layer and ‘sidechain’ networks, such as Lightning or Liquid, created uniquely for Bitcoin.
