I know, but the price is way more than when I buy Bitcoins with fiat money and then exchange them to XC or if I want to sell them, the other way around.
That's true. They charge you some. I would also buy btc with fiat and then get it to an exchange to buy other coins.
That is why I think there should be a site that doesn't sell you them overpriced.
Well they have to make a living I guess
Alas, you'll all just have to wait for XC's decentralised exchange. ;-)
I don't get the decentralized things, can somebody explain to me what that means?
decentralized is no one is in charge ( no 1 person that controls it all )
or
the parts that host or ( make up ) the given programming ( program ) or place
are not centrelized in set locations ( ia multiple NON set locations that can switch all the time )
in case of centralization ( it would be easy for the police to raid a place and take the server down )
in case of decentrilization ( there is no centrelized spot to raid ) so the police and the goverment are fucked
