You could mine other coins with video cards and conver them to LTC, but there is more of a learning curve and you have to keep up with the most profitable coin to mine. The L3+ is easier, you plug it in and get paid mining litecoins. So for a beginner, with super low electric I’d say buy as many L3+ as you can afford, that electric rate is ridiculously low so you should generate a nice profit.
The Giga Watt ICO locks in 3.3c kwh with no hosting fees for 50 years, and they are the oldest mining company in North America. https://cryptonomos.com and their instagram shows bulid out going fast https://www.instagram.com/gigawatt_mining/
When not mining you can rent tokens to other miners generating income 36% at minimum rental rate. it’s worth looking into if you are gonna build a farm, they also do bitmain repairs on site so no RMA shipping back to China. They are sold out but you can contact them and ship your miners to them or have them shipped directly from Bitmain to them or just wait until they have them back in stock. The tokens started at $1 but now up to $1.10 but still a good deal if you’re looking into building a farm.
As for miners we do need more competition than just Bitmain, not just for LTC miners but Bitcoin miners. All ASIC’s need more competition. Wish AMD and Nvidia would enter the market selling miners, would drive up difficulty but also drive down price of miners and make them more accessible to everyone.
