Bitmain tweeted yesterday that they had a November batch of L3+ units for sale again. They are $2040 USD - plus the $115 PSU. They are ONLY accepting BCC as payment (which is bizarre)- no idea why??!! Since there are still some in stock, it means that the market is saturated and almost everyone that wants one already has one. They also STILL have the S9 for $1265 (plus PSU).
The L3+ mines Scrypt coins (I.e. Litecoin). The S9 mines SHA-256 (bitcoin). Using NiceHash, you can mine the most profitable ones. Also, you can buy cloud mining from NiceHash here if you don’t want to buy a miner yourself https://www.nicehash.com/?refby=472276
