What a stupid method, why would people buy the vouchers on eBay? Only complete retards would do so, and I doubt that many of them exist.
Umm.. yeah it may be stupid but people are buying them all day for easily double the price they are on Cex.io. I don't get why someone would either but there's tons of people that I guess don't know how to get Bitcoins elsewhere buying them up. Check the completed listings before you just assume no one would buy these when you really have no idea -
http://www.ebay.com/sch/i.html?_sacat=0&_from=R40&_nkw=cex.io+vouchers&LH_Complete=1&rt=ncTons of people making a living on selling these vouchers on ebay or sites like fiver etc.
And I'm sure your aware the chargebacks on bitcoin related sales are rife on Ebay?
Yes and it should be mentioned, I've sold thousands of dollars of Bitcoins on ebay and you can lose all your money easily. Most the time its people with hacked ebay accounts and you can avoid getting them to buy your stuff by, for example having them verify there paypal phone with you, or there's couple other sure fire methods.
These are easier than Bitcoins to sell but, you should still take precautions, like always having the buyer verify his Cex.io account with you before sending him the code etc. If you take these steps most the time you will scare off hackers.
This being said, I still would recommend selling in small quantities to avoid losing a lot and you may still deal with a hacker from time to time but the payoff is well worth it.
Also, Ebay is slowly (very VERY slowly) but surely taking not and changing its ways with digital currency. Just recently they starting a new selling category specifically for digital currency. I'm guessing in the future Ebay/Paypal will take note of Bitcoins in its disputes as there's a large amount people wanting this and Ebay is talking about completely implementing Btc in the future.
Anyways, Thanks for mentioning!
