I see that the hashrate for this $600 Apollo is in the range from 2 TH/s (ECO mode) to 3.8 TH/s (Turbo mode).

For reference, a $150 Antminer S9 does 14 TH/s.

At the current difficulty level, (which reflects total network hashrate around 250 EH/s), this Apollo device in Turbo mode will produce about 1,400 sats per day (an amount worth about $0.25). Or about $7.50 per month.

Even if you paid nothing for electricity, and difficulty didn't increase from here, and the BTC/USD exchange rate stayed at ~$17.5K, it would take you mining using this for six and a half years for it to return the $600 capital expenditure you made for this device.

The 200W (Turbo mode) will consume 4.8 kWh per day. If you pay the U.S. residential average of $0.14 per kWh, running this device will cost you $0.68 in electricity per day.

So, to EARN $0.25 in bitcoin this device costs you $0.67 in electricity. Thus a NET LOSS of $0.42 per day.

Thus there is NO CHANCE of "break even" (i.e., recovering your Cap Ex spend). You are losing money every single second this device is operating, and the longer you run it the deeper in the hole you go.

Now if you put $600 into buying bitcoin instead, you would have 3.4M sats. If you just sit on that, then six and a half years from now you will still have 3.4M sats.

Compare that to trying to mine using this Apollo for six and a half years where you will simply have just finally recovered the $600 you had spent on the device. And again, those numbers are assuming that the bitcoin network hashrate does not increase from here. As that increases (which it has, year over year, since 2009), this device mines less and less bitcoin per day.
