Happy to share this after a year of mining operations in the US south, what started as a block chain experiment became a full-time gig in Jan/2018 with dedicated mining rig and clustered pools for BitCoin. Keeping the network alive and noise isolated while keeping the facility from heating up too much was a challenge by itself.
But the real challenge was not in mining, but in security, energy efficiency and keeping up with an ever changing miner fees and its value. The power bill surged 10 times that of a regular Data Center usage, despite the warmth provided by the dedicated miners churning blocks and hashes, things were not very warm in terms of the balance sheets.
Update @ Jan, 2021
BTC surged to 28,990.00 USD today, our operations are resuming this week.
