[WTB] Shared proxies without any authentication

I saw so many threads of people selling proxies on this forum i am looking to buy a shared proxy that doesnt have authentication . Like i just enter the setting in browser and i dont get any popup asking for username and password . I couldnt find any details about authentication in description . Can you guide me where i can find those proxies? And payment method is bitcoins .
