IT only draws 24 watts...
I don't get it this thing SMASHES any repeater on the market as it costs the same.. draws the same BUT MINES for you..
1. consider shipping costs-negative or get from a group-better
2. it does NOT mine-it gives you a chance in a lottery, which with your miner being ~1/100000000 of the network, would work out for 1 block in ~200 years at the current difficulty. However, it also means that for every 2000 sold and being deployed 24/7, one will score a block within a ~year on average (with current difficulty), but the other 1999 will produce NOTHING. I did a rough estimate-numbers could be off, but it is what i got.
Well it increases the hashrate of the network and makes it just a bit more secure, it isn't always about an ROI, it could just be about liking Bitcoin so buy the router over a tplink as it involves your hobby.
