The CDC said at one point that the number of Covid Deaths in the U.S. is likely 8 times what is said

 IF we apply this rule to the world that means that around 32 million people have died of Covid Worldwide.

However, I don't think this is realistic because in countries outside of the U.S. and Europe only the richest people get tested or get vaccinated for a variety of different reasons.

So, worldwide I think to be realistic the number of dead are actually between 8 times 4 and 50 times 4. Somewhere in this range. So, the actual number of deaths worldwide from Covid-19 I would say is somewhere between 32 million and 200 million so far worldwide simply because in most countries 90% or more of the people die before being tested. And only those tested before they die are counted in ANY country.
