Kraken (use the desktop website, the app is much worse) is the exchange I would recommend for EU and instead of BTC I recommend buying/using XMR (Monero) as it's a cryptocurrency centered around anonymity, and has lower transfer fees than BTC (and ETH) as well. Completing the sign-up process & verification can take a few days but once you're set up it's quite easy to use, and any questions not answered on their website/via a quick google search you can always ask in this thread, as many here use Kraken.
On that topic, I stopped accepting LTC a few weeks ago - I don't see the coin recovering from the 180€ to 100€ drop of recent months, so I'm cutting my losses on this one.
