Hi tbct_mt2, which is why our Cube 300 does not focus on mining cryptos, but offers to use the computing power in the much more lucrative market of cloud computing/rendering services. You can read more about it here, for example: https://gfxspeak.com/2019/01/23/render-machine-azultec/
Hi AlexaSonda, the Cube 300 will be released in early Q1 2019 and it will be available for the public. We will also release an industrial 19" server version - the WizardMachine 300 in Q1 2019. You can find more information on both devices here: https://azultec.de/products/
