How Much Can I Expect From an Antminer S9?

the only way making a lot profit is making a good rig with like 200 videocards and tap the energy(free energy) haha

price is gonna go up soon anyways, buy now and wait later

I would invest in something like e-whoring or selling social media followers.

For me its waste of money, bitcoin will be cheaper soon ...
