By the looks of it, I guess you're referring to alternatives in Switzerland. Bear in mind that there is a depositors compensation scheme that covers your first 100K CHF in case anything goes wrong with a bank.
Dukascopy is part of the scheme, therefore, shady or not, your money as a (retail) depositor is protected (whether you believe these schemes are reliable is not relevant, in theory "you are protected").
Other similar names that keep popping up here are:
CIM Banque,
Swissquote and Saxo Bank. All mostly trading-related banks, but so far so good as far as I know.
BTW, if the CHF360 (it's CHF90 per quarter...) CIM Banque will charge you to hold your $10K looks 'abusive' in your eyes, ie, a mere 3.6% (a bit less taking currency rates into account), then I think you should start looking in another planet... Swissquote will charge you between 100/200CHF per year for the
credit card maintenance alone, so I don't feel like you're in the right spot here, maybe I'm wrong...just think it over.
