Anyone wanting to mine and actually make it worth it needs a Miner. Obviously an Antminer (or several, depending on your budget) with an Antminer power supply and a 220v line to run the Miner is your best bet for straight BTC mining and a chance at the 12 BTC 'lottery'
I myself have a Dash DR3 miner and powersupply that would run two. The thing is, I dont know the password. The person I bought it from said he did not remember it so I have to format the SD Card for the raspberry and install the DR3 'OS' version. I don't have (or can't find tbh) my SD to USB but it works amazing despite that.
Think I'm just going to sell it to someone, I can provide the GitHub link to the DR3 OS and I could throw in the $300 Power Supply.. Bought originally at $1800 but I am sure the price dropped, and I would probably drop it more because of needing to flash the SD Card.
Anyway, instead of investing in a 'super computer' with several GPUs, which will get you no where these days when it comes to mining BTC (although some GPU rigs work well mining altcoins)
OKCash has been increasing twice as fast as BTC, so if last month you had BTC and saved it to sell it when it hit 19k or around there, you would have had 4x more OKcash, which you can easily sell for 4x more BTC.
Shameless plug from a OKCash Volunteer Staff Member (but I have personally made $100 just talking in the Discord chat; it's really cool and the community is the nicest and most helpful altcoin community I've encountered. Check out the discord:
