I get free electricity but I don't think ltc has much of a future, I would rather just stick with ethereum for now.
I think both coins have a future and in fact although I am mining ethereum I always exchange a big part of it to Litecoin.I always believed in this crypto but the fact is that it is stuck from some time in a low range.I think that halving will not play a big role as it has not done so in the king of cryptos,Bitcoin.
