Comparison with cloud mining
We compare the price of miners with the equivalent of a cloud mining. In the example Genesis Mining and HashFlare. For convenience I carry everything in the table below.
| BW E22 | Genesis Mining | HashFlare | |
|---|---|---|---|
| Hash Rate | 140MH/s | 140MH/s | 140MH/s |
| Price | 2.230 USD | 3.919 USD* | 3.080 USD** |
* The contract lasts 2 years, includes hardware maintenance and power.
** Only 1 year contract, includes maintenance and electricity costs.
BW L21 Litecoin Miner
The BW L21 is the new creation of bw.com Litecoin Miner. It has a mining power of 550MH/s and an energy consumption of only 950 Watt/h. A truly appealing device for everyone. The video below shows the ASIC scrypt in operation, the voice explains the main features of the device. Cost 2.030 USD and it takes 3 months to submit.
