I'll trade my rare tellurium for your bitcoin

[godislove]

I'll trade a 2 pound ingot bar of tellurium for 0.2 bitcoins. It's 99.7% purity, so it's currently worth in China and the U.S. roughly $110.  Maybe slightly lower in Europe. So my current bitcoin price is about 10% high.  On the other hand, there is probably not any other place to get small quantities of tellurium for this price.  It's toxic and should not be touched with bare hands or melted where vapors can be breathed. It is not considered as toxic as lead or cadmium, but you can safely touch lead. It seems to be usually safely excreted from the body like it's sister compound selenium.  Sign of exposure is garlic breath. Harm from exposure generally seems mild and not lasting, but exposure and epidemiological data is limited. It seems to not be cancerous and affecting the nervous system seems like it might require an extreme and unlikely form of exposure such as intense exposure to vapors during smelting.  If interested, send me a private message.  Tellurium is one the rarest elements, produced at about 500 tons per year, used by FirstSolar to produce solar energy from CdTe.  Tellurium is produced from copper mining which contains it at 100 to 150 ppm as an impurity.  If copper production tanks at the same time electrical energy from the desert is needed, then tellurium will increase in value.  A couple of years ago it was worth 4 times more than this price I'm offering, but in the distant past before firstsolar and the metal commodity increase since 2000, it was 1/10th as much.  

Is there a website that can help people trade like this?    It seems ebay and paypal are outdated.  Seller's reputation would be the only "recourse" a buyer has and sellers do not need recourse.  And by using coinbase, conversion to dollars is 1% instead of the combined 15% ebay and paypal charge.  An ebay-like website with bitcoin and using coinbase as the conversion to dollars should add another 1%, but still that's a lot cheaper than trying to be a seller or buyer on amazon or ebay.  Bitcoin should begin by replace amazon and ebay.
