Reddit reviews ASICMiner Block Erupter USB 330MH/s Sapphire Miner

These are tiny USB ASIC miners called Block Erupters, circa 2013-14.

There was a time, maybe half a year, when it was profitable to mine with the 330 megahashes per second that these things could add to your laptop. For comparison, a top-of-the-line Graphics card at the time did about 500 Mh/S, but sucked a ton more electricity out of your wall, and caused a lot more heat, too.

By 2015 these were useless, producing just a few satoshi per day of running the laptop, and are now nice collectors items. I can't even fathom how many days it would take now to mine a satoshi with one.

The ASICMiner Block Erupters. They're actually pretty cheap right now. But you probably will never see any return on them because the mining difficulty is so incredibly high right now.

It's just a hobby of mine... One of my many, incomplete hobbies...

You can pick up their USB miners at retail from Amazon.com. http://www.amazon.com/dp/B00CUJT7TO/

Here let me see if I can find the one's I just bought. Sha-256, AKA BTC Mining Stuff is all ASIC now like these little USB things.

I bought some of those off some dude's dogemining site awhile ago, they make less than 10 cents a day mining BTC, lol. I'm scared to think of the ASIC monsters the people who are making 10's of thousands of USD a day would look like.

I don't think ASIC cards can be inserted directly into a PC, I think they require specialized hardware. Are you thinking of something like this?

You probably won't get much return on these unless Bitcoin goes up by a lot, here's a price comparison of the different hardware you might use if you're going to be mining with USB devices. If that's your goal, it would be a different build for your PC. You'd want to have as many USB slots as possible, or to get powered USB splitters.

> Laptops get really hot mining

OP is asking about a USB plugin ASIC miner
Example: https://www.amazon.com/ASICMiner-Block-Erupter-USB-Sapphire/dp/B00CUJT7TO
The laptop won't get hot. The USB device will

Is dogecoin resistant to ASICs? I wanted to support/hobby mine dogecoin.

Example of one i was looking at: http://www.amazon.com/ASICMiner-Block-Erupter-USB-Sapphire/dp/B00CUJT7TO

And.. draw ~9 tickets for $4? http://www.amazon.com/gp/aw/d/B00CUJT7TO?pc_redir=1405040802&robot_redir=1

Free shipping with Amazon Prime! Now, if only someone could modify an openWRT distribution to act as host for one of these, it'd be a semi-sensible option..

I have bad news for you: given the current landscape of mining you are almost guaranteed to lose money.

Getting a device for mining (an ASIC miner) solves the issue of power consumption, but recouping the cost of ASIC is almost impossible at the moment.

Why? Because there are already tons of ASIC miners hashing away and more and more come online all the time. Lots of people have already paid the upfront cost of an ASIC miner and thus will probably use them even if they'll never break even.

If you want to mine just for fun, consider getting a USB ASIC miner, But beware that you won't earn much coin with it.

If you're looking to profit from bitcoin, the best strategy at the moment is to simply buy some and keep it for a few years.

If you're not dissuaded and want to mine, then we can start answering your questions.

GPU mining died around 2013 when ASICS were nearing completed development and while they tested them, difficulty shot through the roof, and even more once released, which made it more expensive to just power GPU rigs than the coins were worth

EDIT: just one of the latest ATI cards mines about 1-1.5 KH/s. As you can see, for 30 bucks and VERY LOW power, this device can do 330MH/s which is about 300x more.

So this is why GPU mining went down hill. (these were much more expensive 3 years ago, but still.)

I remember this argument was the reason for a mining push back when ASIC Block Erupters (https://www.amazon.com/ASICMiner-Block-Erupter-USB-Sapphire/dp/B00CUJT7TO) first hit the scene in 2013.

Everyone I know bought a bunch of these little cuties, and I think the hashrate did see a tiny, tiny upward push for a week or less.

But then the very next model of antminer or something came out and wiped the previous hashrate level away like it was dust in the wind. Then another 2 weeks later. Then another and another.

Simply put, the hashrate grows way, way way, way way way too fast for this. It will always be economically correct to buy the most efficient mining rig and lots of it.

I suggest you buy an ASICminer Block Erupter. It costs 1/2 as much as a video card and uses 1/150th of the power.

Note however, that in (September?) the price will be dropping to $20 a unit.

Mining with video cards is now a loud, hot, expensive waste of time. Up until a month ago it was profitable in some situations, but now there's really no point.

If you like hacking with hardware (and you seem to be the type that does), you should try running your Block Erupters using a Raspberry Pi as the host computer, and Mine Peon as the operating system:

It's awesome. You just literally copy over the firmware, plug it in, and it works. There's even one guy on the forums running his ASIC miners this way using a solar panel as the power source.

Amazon source to buy these cheap:

At today's conversion rate these "should" pay for them selves in the first 30 days (approx $15 a month per USB device income @ $200 per BTC, and these cost less than $12 each, not counting shipping and electricity consumed. (These consume very little compared to graphics card mining)

TL:DR - For $12 + shipping you can mine your own Bitcoin with a little research (Google it)

Oh something that I forgot, should I just get this instead?

The hub itself is useless for mining, but some miners use a hub like that with a collection of these:

ASIC is a generic term for a dedicated piece of circuitry - for example, this thumb drive. Reading the product reviews, though, indicates that given the current BT difficulty, the return on said specialized device is so minimal that you wouldn't really be profiting.

Thank you for the tip! How do I go about setting one of these up? Do they work with Mac OS X (Asteroid, etc)

EDIT: Well this looks LEGIT -$280

Any Bitcoin ASIC can crack brainwallets. Eg:

Are there any block erupters for Monero? Like this
