I assume that you want to use some kind of middleman,who will run the Google/Bing Ads accounts for you.
Using a middle man increases the risk of being scammed.You must seek for someone extremely trusted and reputable.
I'm confused.Why can't you just sell your crypto for fiat,get a debit card and use it to buy Google Ads?
Is this so difficult for you?
@jitjitmew1, I can't tell you how effective such advertising is, but I can tell you that anyone who is aware of the dangers that come from such ads uses an adblocker and therefore does not see such ads at all. Scammers are massively taking advantage of Google’s inability or neglect to filter out the good from malicious ads, and this has become one of the main ways to advertise phishing links that gain huge exposure.
If you want to find what you are interested in, visit the Service board and use the search with the keywords "Google ads" - and you will get all the relevant results - and you can repeat the same in the Digital Goods board.
AFAIK,paid ads in search results cannot be blocked by an adblocker.Adblockers work only for banner ads on websites(like Google Adsense ads).However,I might be wrong about this.
Google isn't completely unable to track and block malicious links in their Ads.Actually they are pretty good at this and their rules about landing pages are pretty strict.That's why Google makes billions of dollars every year,by selling ads.If the people didn't trust their ads,they would never click on them and Google wouldn't make any money.Most of their ads are pay-per-click(PPC).
