I tried to write something like "usa traffic for website bitcoin" in google but sites i that get is really bad.
Give me some advice please
It is generally not a good idea to purchase traffic for your website/domain name. Most advertisers will be able to see right through this and will deny you payment, even for legit traffic.
IMO, you are clearly trying to inflate the value of your domain and/or are trying to scam the people who are advertising on your website. Regardless you are being dishonest
