Hi Simon, Thanks for your input, I've added Watt column and a (H/s)/W column in order to know efficiency, i should also add price but it depends to much from a country to another.
As this is manual processing there is no one field for each column (Wordpress Form Maker limitation). So I'll put all data's into right column manually.

Hi All,

I've just created a page where one can share your experiance with your graphical card in order to have a benchmark.

Of corse I'm using Claymore since beginning and v8 works perfectly ! Thanks claymore for your job and effort ... waiting for version 9 ... 10 ...

I'm wondering if there is a system that can block a Bitcoin address? (Blockchain blacklist)

If for example, 100 bad report to community... so that no one can use the address to get BTC or to send BTC, sort of BTC black list ?

Hi

I've been also screwed by this so called "Mark Niggerson" (see post https://bitcointalk.org/index.php?topic=231645.msg3736230#msg3736230)
and had e-mail communication with him.

Look like he is in UK ... i know UK is big but maybe someone have better knowledge than me to find people ...

Hi All,

I'm new in bitcoin ... but I trade since 15 year on Internet and never been scam-screwed ...

But this time i failed ... i dont know why ... to much "emotional" factors ... MONEY MONEY ...

DO NOT SEND ANY MONEY TO asic-technologies.com !!!!!!

Of course after my trade and my first experience in bitcoin ... i googled "asic-technologies.com scam" to see that there was plenty of discussion about it!

And i'm pretty sure lot of person are in my case ...

Nevertheless I have a "stupid" question that reply might be NO! ... is there any way to find the person behind ? ...

Hi, i also did my first transaction on http://localbitcoins.com/ with bank-bank transfert in my country. The seller show's me his name and there was also escrow system ...
The only problem is that you will sometime pay your bitcoin value a little more than on other trading place.
