i was wondering buying a small SHA miner (10-30 ghs) is still worth it
not to mine bitcoin.. but maybe some other coins
any help would be great :) <3

No, it's not worth it, and you shouldn't anyway because you have no idea. You should research more before investing in stuff.

lol i was just asking .. plus i didnt mean as an investment

10-30 GHz sounds like your talking about alt coins.  10-30 GHz of SHA is very very small amount to mine with.

Gosh, please, use the right terms. We are talking about GHs, or GigaHashes/second, and you are talking about GHz, which is GigaHertz, which is a different thing.
And most alt coins isn't on SHA-256 anyway, so buying a SHA-256 ASIC is useless for other coins.


Then what do you mean by "worth it"?

It would... But what's the point in investing $40 to never get the $40 back? You might as well give it to me.

hobby vibes... plus i would make it back after 40 months.. in theory

In practice, no, because difficulty goes up over time, and you will earn less and less until you get to a negative profit due to electricity costs.

dont pay for electricity :)

So what. You can obtain nothing with 30GHs. it will be something like this.
1st Month: $8
2nd Month: $6
3rd Month: $4.5
4th Month: $3.375
5th Month: $2.53125
6th Month: $1.8984375
7th Month: $1.423828125
8th Month: $1.06787109375
9th Month: $0.80090332031
10th Month: $0.60067749023
11th Month: $0.45050811767
12th Month: $0.33788108825

It's futile. There simply isn't any 30ghs hardware that will allow you to break even.

  you better off get scrypt miner instead BTC miner and your small miner wont do anything much.

Other SHA256 coins aren't easy to mine. Sadly this isn't reflected in a good conversion rate to BTC either. Take for example Peercoin (PPC). Total network size is about 223TH with a difficulty of 174,600,181. Running a 30GH/s miner you might get somewhere around 0.25 PPC daily depending upon luck. But conversion to BTC as I write is about 0.0015 BTC to 1 PPC. So you'll need to mine about 700 PPC to get 1 BTC or, in the scenario you mentioned, you'll need somewhere less than 70 to break even on the assumption that the BTC price and exchange rate remain fixed as of now. Yet on the basis of this completely unrealistic assumption, it is theoretically possible that you'd be pulling a profit by the year end assuming you still had free electricity. Not to mention that the whole exercise of participating in mining would help you learn more about it and you'd also be part of what keeps these networks decentralised.

Maybe that, together with the fact that you would have easy access to a small trickle of coins to spend would, together with the possibility that they could become worth much more one day (as well as the risk they could be worth nothing or much less!) is sufficient to make the idea a goer for you. After all, $40 isn't a lot to gain a hobby. I could spend that one one meal out or a single dress and not think about it. Plenty have spent and lost far more on sh*t penny stocks which never gave any sort of income! So worth it or not all depends upon what you want as an outcome. If it is to go to the moon, then no, it is not worth it. If it is to explore mining and gain experience in cryptos then it's most likely going to be money well spent. There are too many variables to say with certainty whether you can break even or make money, so doing it with that as a motivation is not to be encouraged because who knows what lies in store for bitcoin and it's pals? Revolution? Evolution? Or destitution? Either way it's going to be fun to be a part of it's history.

ONLY if your mining as a hobby and ONLY if you mine altcoins
