Seems, nobody is willing to do the math... It is a worthless piece of shit even with -free- energy...
18TH mines 0.0007 BTC a day x 365 days = 0,2555 BTC a year without diff and hashrate going up.
Roughly every year the mining power triples, so 0,2555 BTC \ 3 = 0,0852 BTC a year taken in the diff and hashrate rising.
(Again, I do not count energy. Presume you have this free for this calculation)
Even mining 2 years = 0,0852 BTC x 2 = 0,17 BTC mined in 2 years (not even mentioning the diff and hasrate rising in 2020!)
Costs of the miner are (for me in the EU with VAT and import) +- 1300 euro (without PSU) = 0,22 BTC cost of the S9 Hydro right now.
Simply said; You're better off keeping your BTC in your pocket and skip this garden hose miner
