Very good site you have there, nice design

When i saw 100 BTC , i though that is a marketplace for vendors too - i mean someone can register there and sell anything like Alpha Bay Marketplace for example.

Then i figured out that it is "just" a marketplace. So my opinion is that you have to lower the price (yeah i know that 100 is BIN)

Just one thing that i saw,

"Notice: You have javascript disabled. Please enable it otherwise this website will not work properly."

When javascript is enable, it is easy for someone to be tracked down and get arrested. You will have to make it work without java. Just my opinion

If i had some extra bitcoins i would give it a try.

Good luck
