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:-

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

Please help?

When you talk about cryptocurrency, you need to be extremely careful, because their are lots of fake websites online. So if no one you know can confirm this sites to be real and they have made successful transactions before, I would advice you avoid the website.
