I'm not mining Litecoins, I use to. The guide from the site I sent you says Litecoin mining rig, but it can be used for any script coin. I'm minig Dogecoin.
Like you, my goal is to acquire a crypto-coin before it gets big. I don't know if Dogecoin will get huge, but from when I started to now, it's gotten bigger. I started mining in December when it first came out.
The calculations you did are correct for Litecoin, but remember, you can actually end up with LESS coins than than if the Difficulty increases. Back in the summer of 2013 I wanted to build my farm, but got discouraged after reading several blogs. The mining Difficulty was increasing and Litecoin was around $1.50 to $2. so mining (like in your calculations) wasn't profitable at all. Because of the mining Difficulty level, my electricity was costing more than I was earning in coins (no 3x return ROI). Well I didn't build the farm in time and as you might know, Litecoin went from around $2 to almost $50. Had I eaten the cost of electricity and just mined and stocked the Litecoins away, I'd have gotten much more than 3x ROI.
So we're facing a similar situation again. If you chose to mine Litecoin, you know that based on your calculations, you might at best break even within a year if you're lucky and the mining Difficulty doesn't increase to put you completely in the negative category in terms of profit beyond the year. So you have to decide if you believe enough in Litecoin or any coin to eat the cost of the hardware and electricity in the hopes that Litecoin or any coin you mine, increases enough in the near future to give you that 3x ROI.
I am currently on the plus side right now with Dogecoin. I'm not 3x ROI, but I'm doing okay. If Dogecoin goes mainstream and some of the projects that are being worked on takeoff, then my ROI will be much much more than 3x.
Give this Reddit ( /r/dogecoin )site a quick look, they are much more welcoming and share lots of info. BitcoinTalk.org isn't very friendly.
I figured that was your objective, it is a some what tough decision because the projection is not quite clear at this moment, at least not for any other crypto currencies besides Bitcoin. Actualy my original investment was opted for BITCOIN, given the current coin value and the powerful ASIC miners in the market.
THE PROBLEM IS, its too much of a scam right now out there to get my hands on miners with enough power to build a 24 terahash rig. Like i said, the money is not the problem, theres always a way to finance, but its too damn risky to deal with people who are offering complete scams. Im going to keep an eye open but i made calculations based on the bitcon hashpower of 24 Terahases and the dificulty and if i get my hands on a rig that costs me $300K ASIC miner optimezed, by the end of the year, working in a pool and that kind of power, lets just say, id have enough to buy any kind of hashpower id like.
It sucks that too many people are currently trying to scam you when talking of serious dope, but i think your on the right track, just keep eyes open for what happens in the market and im sure ull be able to trade your coins at the right time!
Ill look into the info u sent.
