Crypto mining is hot – literally. The equipment used to mine bitcoin and other cryptocurrencies generates significant amounts of heat and noise.

Heat generated by computers is nothing new. Engineers have been using liquid cooling to help powerful computers run more efficiently for years. But no one was applying liquid cooling to crypto mining. Until Hydro Hash.

Rick Bentley and James McGibney are on a mission to make crypto mining more sustainable through Hydro Hash. They’re starting with liquid cooling – but the mission doesn’t stop there. Power sources, mobility, and efficiency are all major concerns as well.

On this episode of Inside Startup Investing, Chris Lustrino gets a crash course in cryptocurrency and crypto mining from Rick and James. From the difference between proof of stake and proof of work to the question of whether a digital currency is the future of crypto, this conversation covers all of today’s key crypto issues.
