One thing for sure. It wont be profitable to mine with them. So, since there is a lot of hype with bitcoin mining, it might be worth it. The only way to find out is to do a test. buy 20 of them and see how they sell..
Risky stuff, better buy BTC ale hold 
Topic: Is it profitable buying and selling USB miners? - page 2. (Read 1601 times)
I am actually surprised people still buy USB miners, cant even pay for its electricity 
Haha. I think it wouldn't be profitable to that. Fees from paypal and shipping will eat up your sale. Plus, as the bitcoin difficulty increases, miners value would decrease because of the fact that they can't keep up with the change in difficulty. Because of that, it won't be profitable to mine with them and I don't think people would be interested in buying them 
And don't forget the ASIC price will keep going down with uprising difficulties and newer generation ASIC keeps rolling out.
Don't forget ebay/paypal fees + shipping. That will eat some up there.
That model is no longer made so cant really buy in huge bulk. Unless someone is hording a stash (which i dont see much reason on these). There is a chance of profit just make sure to subtract fees.

You would get profits from buying low and selling high for everything, but there are 2 problems here.
1. You have to include shipping costs
2. For those BE, the electricity cost will be larger than the bitcoin you can mine with them.

For example, on eBay.
I've seen auctions where a single Block Erupter was sold for $20. The AntMiner USB ones tend to be a bit more expensive per unit but cheaper per gigahash. I've also seen Block Erupters being sold as low as $9 each - usually when they're being sold as a group. Say, for example, if I could consistently buy Block Erupters (BE) for $10 each and resell them for $15 each, by the end of only 20 trades, I should have:
$0 (1 BE)
$15 (0 BE)
$5 (1 BE)
$20 (0 BE)
$0 (2 BE)
$30 (0 BE)
$0 (3 BE)
$45 (0 BE)
$5 (4 BE)
$65 (0 BE)
$5 (6 BE)
$95 (0 BE)
$5 (9 BE)
$140 (0 BE)
$0 (14 BE)
$210 (0 BE)
$0 (21 BE)
$315 (0 BE)
$5 (31 BE)
$470 (0 BE)
So that would be a profit of $470. Not only that, but these Block Erupters could also be used for mining when they're not being bought or sold, which should give me a couple of cents worth of BTC at first but possibly a couple of dollars after the first 15 or so trades.
What am I missing here?
