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.
Payment after the approval of the page indicates a behavior of distrust of the second party, if you do not trust them, do not publish using them.
The parties that are worthy of where to pay are reliable.
Tip: It seems that you do not know about marketing, posting an ad will not help you increase your press followers.
Hire someone with marketing skills that will help you.
