If you are interested in litecoin then buy it from www.hashflare.io. Unlike genesis-mining.com they have lifetime litecoin cointracts but the contract pays in btc and not in ltc itself, I don't know why but I am ok with it. The cost of litecoin contract is almost 13.5USD per MH and cost of electricity and maintenance is 0.01 $ / 1 MH/s / 24h. I have purchased 28MH litecoin contracts and since the price hype of LITECOIN I've been making almost 0.0015btc income per day and maintenance cost is 0.00018btc which make final output (0.0015-0.00018) 0.00132btc. Another feature of hashflare that I like is you can reinvest to upgrade your contracts from within the panels itself using your earned btc itself.
