Hi guys,
The other day searching Quarks info I see this contest,so here is my try.
I readed from avoid gold from logo because BTC is associated with it.One of my versions it´s made with gold,but not only gold, I think Quarks can be a mix of gold+tech+little bit of "radioactivity" and modern too.So one of my versions is based in that idea an the other has a white modern look.
Hope you like it.
