Well I'd buy a Ferrari and a new BMW K1200R but if that's not your bag then if I were in your position I would put it somewhere safe - your bank in Switzerland will be able to advise you, don't expect high returns but you won't get ripped off with charges either, and avoid (almost) any chance of losing it.

Avoid these people. Pretty sure they trawl the EF and other sites looking for 'clients'.
