Are these crypto exchangers LEGIT ?

I stumbled upon these sites, but as I am new to cryptocurrencies I don’t know if these crypto exchanging sites are legit:-

https://btc-change.top/
https://vechain.live/
https://ctb.pw/

Are any of the above sites legit and I found these sites here:-

https://cryptofun.club/
https://exchangerates.top/
https://antonio-job.best/

Please help?
