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.
Those top news websites you mentioned above will charge you huge amount of money in one single article for a PR and Coolcryptovator is right they will never allow you to pay later they are not bounty hunters lol , but if you really want you can contact them and ask your proposals for payments but I doubt they will agree.
