I want to publish Press Release on crypto websites like:- BBC, Bloomberg, Coindesk, Cointelegraph, CNBC etc and I also want to create a page on Wikipedia but I will make payment after the approval of page.
For starters the BBC doesn't accept advertising at all so that's a complete no go, although they may be interested in your news for their technology pages. Equally, the others may accept your press release if it has a strong enough news angle to it that will interest their readers, but with editorial there's no guarantee.
If you want to guarantee publication you'll need to pay, and media outlets like Bloomberg charge a lot of money. And I mean a
lot of money so you'll need to have deep pockets.
Bear in mind that there's a lot of PR you can do for free if you manage your social channels correctly and have your own website to host your material (which is cheap and easy to set up).
PM me if you need any more advice as I've worked in the media sector for many years.
