I was thinking of buying 4x Innosilicon A11 Pro 8 GB for ETH Mining. I got access to industry electricity costs in Germany, so I get 0.16 EUR kWh. My initial investment including cables etc. would be around 20k EUR. The ASICs are available at the official site at https://innosilicon.us.com/product/innosilicon-a11-pro-8gb-ethereum-miner-2000-mh-s/. I will buy 3 and get 1 free.
What do you think? Is it still worth to invest in ASICs for ETH mining, especially in Germany? I would like to hear opinion from experienced miners preferably
