The profitability of such equipment is reduced after the introduction of each batch. Antminer L3 has been released for a long time. Therefore, I do not see any prospects in purchasing such equipment. I recommend you wait for the release of new equipment. A good income, you get only the first few weeks after release. The rest of the work is just a bonus.
I recently made a large amount of profits in cryptocurrency, and with that money that I made I was thinking of buying the L3+ antminer (about 15) to mine LTC. In this thread people are saying about buying the miners with USD and in my case its with crypto which I profited so I am not loosing a lot (I will gain the initial investment within a few months depending on the price of LTC), and about electricity, its cheap in my place, I am looking for peoples opinion in my case.
Also the miners are cheap at around 880USD which is a decent amount. I dont know for how long it will stay this price.
Thanks
