Question: Essentially what the above implies is that Hashgraph will make MINING Crypto tokens obsolete thus negating the need for expensive mining hardware. Envion business model is around "Scalable Automated & Cheap Mining". So does Hashgraph have the capability to make Envion obsolete?
No, if there is no more demand or better said it is not profitable to mine anymore, then you can use the computing power for blockchain and offer it to the industry.
