Hey ppl. I'm thinking about buying 3 antminers that generates ~300mh/s
I need to know if it's worth. I'm not ambicious, I am doing that as an experience but I expect to end with something.

If these are the old USB ASIC eruptors, they should be used for educational purpose. They will generate virtually no coin for you. You can join a pool but I guess there is a minimum amount for withdrawal, which you might achieve using the miners running at a few hundreds MHash/s.

I would go with one of sidehacks usb sticks. They are much more current then the old block erupters, and they don't cost that much more. Block erupters cost a fortune for what your getting. But no usb stick miner is really for ROI. Education and lotto are the two options for them. And lotto is ... like running with almost 0 chance of hitting blocks if mining btc.

But look at compacs if you really want a usb stick miner to learn with.

U1 1.6-2.0g
U2 2.0-2.6g
U3 63g
S1 90-100g (old single blade)
S1 180-215g
S2 1000g
S3 440-500g
S4 2000g (I think)
S5 1100-1400g
S7 4700g

So not a bitmain product that I've ever heard of. If it is a 333mh/s one that is worse then a GPU and may not even be able to get a share anymore. Last time I used mine it was like 90 minutes to do one share from a pool and that was months ago.

I concede that point. It could indeed be an ASICminer single ASIC chip on usb which I was thinking of, at about 300 MHash/s. It certainly was not a U1.

I still think that an S1 or something > 100 Ghash/s is the minimum which I could recommend for educational dabbling and gaining experience.

I wonder if folks are mixing up Antminer with ASICminer. The reference to 300 MH/s sounds about right for a single ASICminer stick (which was actually 333 MH/s). The smallest, lowest hasrate, Antminer I ever saw was the U1, which was 1600 MH/s.

I think OP was talking about a classic ASICminer USB stick.

It's great for education, but not for making a monetary profit.

The first antminer usb stick really was 300 mega, and if plugged into a raspberry pi it could equal the output of an average gpu. That was good in 2013, but not so good now. Look up bitcoincharts, and find a link to some more charts which show how the difficulty has gone up.

I use second hand S1 antminers, which are similar to 64 chips from the next higher model antminer-usb stick. One S1 gets 160 to 200 Ghash/s depending on underclocking settings. Whilst I do get hashpower envy every time I look up specs of an S5 or an S7, at least I'm within my power budget for home solar electricity experiments.
I can say that one S1 is about the minimum to see any output at all in a day from many BTC pools (or a month from some pools), and is better reconfigured with cgminer from hashnest and mining altcoins which appear in my home altcoin wallet quite frequently. If for purposes of testing how it all works you need to see enough bitcoin to be allowed to transfer it to your home wallet, the S1 is probably the smallest sensible. By the way, I also use it to help with warming up my computer room in the winter.

More specific advice from me I'll do for 0.1 BTC so pm me if you might want to buy configuration info.

This is the only site you'll need:

http://www.coinwarz.com/calculators/bitcoin-mining-calculator

Plug in all your variables (hashrate, power consumption, electricity price, pool fee) and look at the output.

Keep in mind that the block halving is only a couple months away, and the diff might still rise, also it's not guaranteed that the price will rise. So you should consider the output of this script as a best-case scenario for the next couple of months, and a big over-estimation for after the halving!

300 mega is a bit ridiculous, you perhaps mean 300 giga or more, you can buy 1 s7 if your electricity rate is good enough, usually below 0.05

but at no more than 1.5 btc total price

Bitcoin FTW!

As long as electricity is not a concern, consider buying an antminer s1. They're built like tanks and last for so damn long- in fact I have one from 2013 that still hashes and runs like new! 360W/180GH/S full hashrate, or pencilmod for near 1w/gh.Will never make you money, but great for experimentation and beginners. If you like a miner you can REALLY work with, buy a Gekkoscience Compac from amazon, ebay, or bitshopper <--- best price if you live in the eu but shipping kills it for us muricans ;-; Lots of documentation and you can mess around with it. 2nd most efficient miner out there, but won't make you money, if at all a penny a day or less. .3

I don't know of any antminers that are 300mh or even 300gh. 300mh is slower than a decent GPU 300gh will work but you most likey will not make enough to pay for the miners and electric.
