Re: Crypto mining in general
If you want to mine bitcoin you'll need an ASIC, but some crypto's are ASIC resistant, ethereum is supposed to be one of these and they do it by using an algorithm that requires a lot of memory which takes up a lot of chip space.
Blockchain is finding more and more uses, a US healthcare provider is using it to store patient data and it lends itself to tamper proof accounting systems very well. They can use their own systems to build the blockchain but at some point it's going to be simpler to farm this out and if they can create a coin/token for their blockchain it's conceivable that instead of popup adds on your smart phone app you can rent out your processing power instead.
