Can I purchase the domain, and if so, how much does it cost? Do you have any estimated price range for the domain?

In my opinion, the domain is worth at least $1000, but the maximum price depends on the buyer's willingness and ability to pay. The popularity of the .site domain, which is even better than .pw, should also be taken into consideration. Looking at previously sold coronavirus domains, this seems to be a reasonable estimated value.

Regarding the use of the domain for a blog or website, there are many potential topics, such as disease distribution zones, medical centers where diseases are treated, and news and discussions around treatments. Unfortunately, a good domain name has already been taken.

I think that coronavirus.site can cost up to 10 thousand dollars. If there is a suitable buyer.
But it seems that the pandemic is on the decline, and if you don't sell it in the next couple of years, then the price of the domain may drop significantly.
