Make up your mind - Bitcoin or Altcoins?
Bitcoin mining has been ASIC-based only for several years now. I highly suggest you start by looking through the
Beginners and Help section and then head over to
Mining (Altcoins) area.
Hello OP, i also suggest you do what fuzzywarm has suggested. Your question is... seems like you need to do alot more research before you start spending funds to start this mining facility of yours.
There are alot of calculators online to give you a rough estimate of what you can earn. You can easily type in the specs of hardware you are looking to purchase so you can make a smarter decision.
Bitmain currently selling 14th s9 atm. But this is presale for december batch.
Goodluck.
