I need your advice.

I will buy this domain and switch to my website.

Different languages, different contents, different keywords

The domain to be purchased has strong links and quality. Can I take it over in this case?

This is a website that was created in 2000.

I will buy it for 1,000 dollars. Do you recommend this plan?

It's down to your personal preference. Only you know the real worth and if you can maximize if. If I got $1000 available I would start working on my own project. I just pray I get 500 dollars within 2 months

I agree with @mahmud daud . It is nonsense if you want to buy this site for 1000. If it will be on myself I will make my own website.
