.05 per day per antminer is very good. I wouldnt change a thing. I am making about .039 I think
He is making 0.05 per day for both. That is about 32 usd per day. Assuming he's using 900 W (overclocked, otherwise daily earnings would be a bit lower), that's 21 kwh/day. At 0.15/kwh that is 3 usd per day in electricity, for a net profit of about 29 usd per day. Over a three month period that translates to spending a bit under $300 for electricity and around $1400 hardware cost.
The point I am trying to make is that if this a profitable business model, with difficulty going up every 10-12 days it will take long time to break even.
He will break even on hardware in probably 50 days (after factoring in electricity) and from that point on be making a profit. Will he get rich? No. Will he make some money? Sure. If you could make enough per month to cover a car payment after 50 days why not?
My goal is to make enough each month to cover child care for my new and first baby coming up.
You don't lose any shares or BTC,it keeps adding up but it goes into failover or whatever & the payouts are delayed
