Apart from KNC (Sweden, right?) there is Bitmine AG. A Switzerland based/registered company, so not EU but Europe.
The website (
https://bitmine.ch/) looks legit and the background info they provide as well.
But you have to check it out yourself.
By the way, I have no experience with them or connection to them.
So you have to do your own investigation and I'm sure you'll find more info in the forum.
