Litecoin mining need tips

[sale666]

Hello people, i got interested in mining litecoin but its hard for me to understand at what stage is litecoin at the moment?
Is it fully script asic miner oriented as bitcoin or is a rig with g cards still an option?
Some 1 shed some light please .

Cheers

GPU mining for profit of any Scrypt coin (specifically including Litecoin) has been impossible for 2+ years now, unless you have FREE electricity - and even then your GPU will probably DIE before you manage to achieve enough mined Litecoin to repay the cost of the GPU.

 The fastest GPUs never managed to even get up to 1 MHash/sec - while eating 200+ watts for the ones that even got into the BALLPARK of that rate - while my A2 Mega Terminator units achieve 110 MHash/sec on ballpark 1200 watts power usage.

 Even the old Gridseed 80 "Blade" units managed over 5Mhash/sec on ballpark 100 watts power usage (mine were mostly manageing 5.4 at about 90 watts with brick power supplies), and those are NON-PROFITABLE today unless you have VERY VERY cheap electric.




 non-SHA non-Scrypt coins can sometimes be mined for a profit with a GPU, and if your electric is cheap enough you might even manage RoI on a GPU-based rig in a year or two, but forget Scypt mining with a GPU.

Thanks for that info.. What scrypt asic is in the lead today with a company that actualy exsists since there are many scam ones..
I curently am negotiating for a 1 megawatt solar facility to sell me power really dirt cheep and im planing to invest money into miners..
Of course there in no way i can use 1 mega watt i was thinking 10-20kws of power.. Would add uo to 10-20k € of equipment..

As of right now, a working Titan has the best efficiency (I am not counting the Sfards SF100 unit, as those are very rare and apparently Sfards has abandoned trying to sell the things any more) - but Titans have a long history of having one or more of the die on their chips die, they are almost as "overpower the PCI connector" in their board-level design as their Neptune design (which has been documented to START A FIRE on at least one occasion and has been talked about having done so on other occasions due to how overloaded it's PCI connector and corresponding power traces on the PCB are), and just generally was not a good RELIABLE design.

 Next is a tossup between an A2-based unit and an Alcheminer (efficiency on both is pretty much equal, close enough that individual unit variation matters in ranking them) - the A2s variants are a lot more common. A2s have a long reliable history, Alcheminers have a shorter history but seem to be good on reliability as well.



 Innosilicon announced tapeout on their next-gen A4 Scrypt miner chip several months ago, based on their posts miners based on THAT chip could literally show up any day
 (along with their A3 SHA256 next-gen chip).
 The Alcheminer folks have announced they're working on a next-gen Scrypt chip as well, but seem to have less financing available and aren't as far along with it.

Thanks for the info man its really helpfull.. Im curently negotiating with the owner of the power plant as he would offer me a kw/h for 5-2 cents and thats very very low it just depends how much i would use as for now i cannot use 100 kw because that would mean i needed ~75 miners s7 for btc if not scrypt.. And thats a huge investment atm for me was even thinking to offer hosting to people if they would give me a percentage of their earnings!

5.2 is low, but not really VERY VERY low. Bloody cheap out of solar though.

 Hosting is normally done on a cents/kw/hour type basis, NOT on a "shared profit" basis. You charge some price at a higher point then what you actually pay for electric, they get the profit but pay YOU a flat fee per hour (day/month/whatever) is the normal arrangement on hosting.

I see thanks for information.. Hmm you got me wondering because depends on how much kw's i use the price goes down so we start at 5 cents per kw and if get more and more we can drop down to 2 cents per kw.. Im my calculations if lets say for btc an s7 draws 1.3 kw per hour that makes 936kw per month if its 24/7 on... And if i use highest bill its 47€ a month electricity but the miner makes 175is~ € a month so thats a good profit and margin if im not wrong?
So if i multiply that with 20-30 miners i plan to buy myself + let people host for a fee just so i can lower my bill down to 2 cents a kwh than that makes a superb deal even if i would mine with antminers s3!
Am i missing something here or i forgot to add something?
Cheers

Abandon proof of work mining, switch to Gridcoin if you've got GPU's.
