I bought an A4 Dominator months ago and I think it was worth it. I was making about 4-5 LTC with it a month, obviously decreasing overtime, 2-3 LTC is reasonable for now.
The machine itself is durable, I run it and get about 250Mhs consistently, very set-it-and-forget-it, it gives me no trouble. Calculate your ROI at 240Mhs to be on the safe side. I don’t think the A4 Dominator is a stupid idea but I do think it’ll take you 1.5 - 2 years to break even so only do it if you’re looking for a new hobby. (If you’re trying to strike it rich, probably better off buying the underlying asset with your $1400.)
Lately, I overclocked it and I get the 280Mhs as advertised and it still stays pretty cool even though I don’t have it in a chilled data center. (Just in my basement.) I watched A4s on eBay for about a month before I got one at a good price at auction, I think 1400 is a great price, next month, 1300 would be good, next month, 1200, etc… I think at this point, getting an A4 would not be stupid but it will not make you rich either. If you don’t have an isolated place where you can run it and let it be loud and hot, then you probably don’t want to get it. It’s hot and loud.
Think about the economics for a bit before you get into mining. For me, I mine because I like computers and I do it for the sport of it as well as the service I provide to Litecoin network. (I just started running my own node and mining solo.) I’ll answer some of the questions you got and let others correct me where I’m wrong.
Not exactly, as the price goes up in value, the more people will want to mine, the more miners that are mining, the more difficult it is to mine. This is because the difficulty is adjusted to maintain the time to find each block at 2.5 minutes. As blocks are found faster (say 2.1 minutes because there are a lot of people mining) the difficulty increases. The difficulty is no influenced by the price, the difficulty is influenced by the network hashrate. (Which happens to increase as the price increases)
Depends, why do you want to mine? Think about the economics for a bit before you get into mining. The miner requires a fixed electricity cost which for you is going to be like $75/mo. The reward you get each month will be 2-3 Litecoin (maybe 200-300$/mo) but will be declining. And the value of the machine will depreciate (i.e. you will be able to resell it but for much less that you got it).
For me, I mine because I like computers and I do it for the sport of it as well as the service I provide to Litecoin network. (I just started running my own node and mining solo.) So it makes sense for me becuase I enjoy it, I value that enough that I’ll keep my miners runnning as long as I break even on my electricity costs.
Sounds about right but remember that will decrease every week and there’s a good chance it could decrease by 50% in 3-6 months.
Personally, I like the A4 Dominator, I think the machine is a work of art. I like the A4+ better, I would recommend going all in and getting the A4+ if you have the means. Don’t waste your time with second hand equipment. Your friends selling theirs at 1400 because they’d rather take that 1400 and put it into crypto than mine… If the machine was such a money maker, why wouldn’t your friend keep it? He knows that the difficulty will make the machine useless in 6-12 months so he’s selling while the hype is high, I’m thinking of doing the same with my A4 Dominator since I have a better machine now. (And my better machine is better than the L3+!)
Good luck buddy!
