Antminer (or other)

[rizabbasi]

Hi,

Is it still profitable to mine with S3, S5, or S7.

I have two options i.e. to go for BTC or research on some altcoin. Altcoins are numerous and contain risks. Bitcoin is established and proven but contains ongoing high complexity.

Price of electricity in my part of the word is 19 cents per kWh.

Please advise about the Antminer or reasonable altnernate.

Regards,

Riz

None. Not even GPU mining would work at that electrical price. At this point just erase the concept of mining from your brain- there IS NO way you will ever make money with miners. Unless you have electrical costs below 10 cents per kilowatt, you can't even begin to think about bitcoin mining.

Just as mentioned above you should not proceed to buy miners and those miners you mentioned is outdated already since the latest one is s9 miner and considering the electricity cost on your place i would really say that its already a bad idea to mine bitcoin and if i were you i would choose to buy bitcoin itself rather than on mining it because if you will mine you would surely waste off your time and effort and ROI would be very long.

i don't guess S7 is that profitable, because you are needing to deal with 2EHash using just a few Thash.
unless you are lucky enough, i don't think those miners are great enough.

If your electricity cost is 19 cents per kWh than simple don't dream about mining by s7, all previous miners which you wroted are useless now even with free electricity. If you can buy antminer s9 but with such high electricity prise, it's still not profitable. It will be better to try altcoin mining with GPU or there are some altcoin miners, I can't remember their names.

You have a point bitcoin mining is not profitable nowadays no matter how cheap your electricity is and lets also consider the mining difficulty on bitcoin which is already high thats the most reason that most miners having a difficulty on achieving roi.As you suggested i will rather choose altcoin mining because we could always exchange it to bitcoin and mining difficulty isnt that high.

If you have free electricity, you can get a little bit profit from mining but it's not worth mining.
you can use these mining machine for another new altcoins .
