Hey, guys, I want to buy asic usb miner 330 mh/s. And now it will make $28 per 24 hours. Is it possible? Maybe some of you have it and get the same result?

Not yet, but I want to buy, it cost $30-40 on ebay

Maybe. So, how I understand it can mining only bitcoin? Or  ethereum too?

I don't understand the $30ish ebay market price. They are worthless considering you can get a 2pac for $80 which can run at 15 g/h. You would think people could figure it out with a little research but I guess not.

Please I am complete mining novice. I have tried severally to mine with my pc but no avail. Please what do I need to install to be able to do this?

I wouldn´t say that USB miners are the past. Like I see it there is no profitable way to mine bitcoin any more.
If you want to keep it simple try a gekkoscience 2 pac. It´s an USB miner with an overclocked hashrate of 15 Gh/s. I think thats pretty good for a USB miner. If you want to make a little more bitcoins you need a real mining machine. But then you have to consider the power consumption. I have running two 2 pacs with 10 Gh/s with an input power of 25 W. The raspberry pi and the fan included. That is payable.

Ughhhhh!!!! How do i install this on UBUNTU!??!!!!

Which one do i download!?  Uggggh

"No doubt you are doing the wrong thing anyway. I'm guessing you think you can install cgminer and mine with your PC. CGminer is controller software for dedicated mining hardware, it does NOT mine bitcoin on your PC."

I made a dedicated mining rig with one gpu (for now) with Ubuntu OS. I've got a ledger on the way from Amazon and am currently trying to get a miner running. I attempted Easyminer and got an error. Now i'm trying CGMiner. My challenge is that I am a Windows user and a complete noob to Linux.

I am glad everyone on here is quick to help or be an @$$hole.

Right so you are doing the wrong thing. You cannot mine bitcoin with a GPU and cgminer. A GPU is not dedicated mining hardware.

Ok. Thank you. However, I'm not interested in mining BTC.

I want to mine altcoins. Is this where you are going to tell me to post in the Altcoin forum?

I thought I was in the CGMiner part of the forum?
