QTUM demonstrates the often-discussed argument that other block chains can work, and Bitcoin can better handle network effects. QTUM does not believe it is a network effect, but it provides all the functions of the Ethereum token and distributed applications to provide additional mining networks and potential nodes.
However, transactions are becoming scarcer and more expensive. Developers can create applications for multiple platforms, and QTUM can be used in the future as conditions change. In essence, all of the scalability improvements and limitations of Bitcoin are available.
