A few questions from a beginner

Hello everyone

I have got a few questions since i want to start using coins.

First where should i buy coins using fiat? I am based in Germany and i tried to sign up with Kraken. I am waiting for my verification since a few days though.

Which exchange platform and wallets should I use and which to avoid?

And who to follow, what to read; so basically where to get all the infos I need.

Im also happy about any other usefull adive.

Cheers
Dorman
