The profitability of USB miners

[Cascadia]

So I see these USB bloc miners going for $30-40 a pop.. They claim 300Mhashes/sec -- but how feasible is it to mae your money bac and actually generate a net profit with these USB devices (whether or not you tae into account overclocing the chips)?

I'd appreciate some input regarding this.

short story - they aren't.

You can check out here - with the new difficulty bumps (no doubt contributed by the miners) they aren't really profitable unless you basically have free electricity.  And even then it will take a super super long time to make back your money.

I got a whole bunch because I was curious.  A horrible investment but I also wanted to just try my hand at generating some bitcoins and they are SO LOW POWER over my GPU that I figured why not.

GPUs have the added benefit that they can also mine other currencies besides bitcoins... the asics ones can only generate BTC.

At this point in the game, you're never going to make your money back if you pay for the electricity.

Yeah, that's what I thought.

Without starting a new thread, are you guys familiar with cloud hashing? I've seen annual contracts being sold that have "2 Ghash/s" of power. I was also curious about the feasibility of this route (or is it basically another "won't brea even" situation)?

Just buy BTC, you can earn more that way. :/

That is not cheap!

It's 90 to 120 dollars per GHash...

How many Ghashes would you say one would need to be able to harvest a single BitCent on a 24 hours basis?

I'm looking at about 2GH/s

Hoo... Then it's definitely too late for me to mine, haha!

Thans for all the responses guys, it was very helpful.

And with these prices: http://www.asicminer-shop.de/

2 GH/s cost 1,734 BTC, not counting shipping, and in the next year they will earn 0.75 BTC: http://mining.thegenesisblock.com/a/5d57d1a257

Not good business...

And it's never too late to mine, what you need is to find cheaper GH/s...

Yeah well bitcoin diffulcy has increased greatly....  BTCguild PPS has pretty much went from 0.00000060 to 0.00000020

not profitable, maybe many months to get roi
best to buy cheap usb miners, mine on them while waiting for buyers and resell for profit

[Professor James Moriarty]

If you ask me if you could buy for 30-40 bucks per usb thats a good deal and good roı , but at one point it was .99 bitcoin per usb which was horrible
