Don't sell it for anything cheaper then your asking price. Current price of dash these days makes these miners hot little items right now. Heck I saw one go for almost 900usd on ebay 2 days ago.
Funny how people pay so much when you can get these for cheaper even on a site like Aliexpress. eBay items are naturally priced higher than other items elsewhere and generally it's not too good of an indicator for pricing; where S3s sell for 80+USD on eBay, I can easily get one for thirty including shipping on the forum.
Yes...I agree with you, and how about those S9's fetching upwards of 4 grand on ebay.....almost makes me wanna buy a shitload at bitmains next release just to resell it them....but I dont trust ebay/paypal seller protection program.
