This is Antminer S9.
You can't mine the freaking Dash with it.
Only Bitcoin and other sha-256 cryptos.
Im staring at linked picture from above(wearing lenses, so my sight is kinda foggy at the moment) https://i.imgur.com/M5nAqQu.gifv
And i am thinking all of everything that you have written.
Before i jumped on buying miner train, i had like 4 weeks of sleepless nights, it was so awesome reading all this about new crypto world. How everything works, what are miners, nodes, bitcoin. What is purpose out of everything, how each miner works. You cant just jump into something like "i haz money me not work me get money". Just dont be dumb and use damn GOOGLE for anything! There is no stupid questions!
