I'm gonna spend some of my bitcoin for buying a new graphic cards.
You mean computer hardware? Where you will go to buy it with your bitcoin ?
Well, if you want to buy a computer hardware. You can check it here https://bitcointalk.org/index.php?board=75.0
And if you can search it, there's so many users selling a graphic card.
Oh yes of course trade in this forum more safer i think than have to purchase in weird new sites.
Unless there are a trusted website proving experience years on selling that stuff. Until now i cant see it.
