Looks very unstable, but guy is probalby minning some ubercrapcoin. Eitherway L3 looks nice but given S9 issues and first scrypt miner from Bitmain, i wouldn't trust it. One breakdown a year and you will lose all you gained from electricity.
Not to mention the 11.56 difficulty rise in LTC.....this is getting "interesting' in the worst way.....flat LTC price more or less over the last months....more
scrypt miners out...like toasters................need some price action to compensate in some manner imho
Have not looked but what is it ...difficulty on LTC up over 30% and we have not seen the full push on A4's or L3's yet imho...
glad I waited to buy...again need a pump in price to offset this in scrypt pow and LTC as a specific notion....
