Payback period of Antminer L7
Let's use the BiXBiT calculator to calculate the payback period. So, with the given characteristics and the cost of 0.05 USD per 1 kW/h we see the following numbers:
For DOGE with the rate of 0.25 USD - 110 USD per day, 3,300 USD per month. Thus, for Western buyers, the payback is 3.9 months.
For LTC with the rate of 150 USD - 26 USD per day, 780 USD per month. Thus, for Western buyers, the payback is 16.7 months.
You can also check the payback period for other cryptocurrencies in our calculator. The most profitable for mining is DOGE, but this is relevant while its market value is at a high level. The profitability of other assets does not exceed 30 USD per day, which significantly increases the payback period of the device.
