It's tough to tell other how to invest their money...but EOS is very tempting. Even it it takes a while to catch on...dan sure seems to know how to make great stuff!
On the wallets, it's tough for me to say much on the other wallets since I haven't really tried a ton out myself and being US based. But I have seen people say good things about bitwala which looks like is available in Germany. It might worth seeing what people in the @german-trail think..just to ideally get a first person perspective on it.
