Cheap?
Really difficult to justify $500 for 2 Th/s. $250 per Th/s vs $55 per Th/s for an S19 Pro. Energy consumption also not great...equivalent to running 6,600 watts vs 3,200 watts.
Assuming this is it:
2-3.8 TH/s of SHA256 performance per miner (+/- 5%) 125 Watts in ECO mode, and 200 Watts in TURBO * +/- 10%

So, punching the above number into the Hashrate Index calculator:
This will generate $0.38 per day, at current hashrate and bitcoin difficulty. That's ~$140 / year.
Even if you get free electricity, this will take about 4 years to return the $500 you paid for it (again, at today's BTC/USD and bitcoin difficulty)
Don't be an idiot.
