If that's the only reason why not use a web or mobile based wallet? Personally I never had much of a problem with the qt client, even when I've let it get out of sync for a month or two, but if you're having such issues it might be a sensible move.
I'm actually unable to log into the web wallet at the moment. It's been down the last 2 times I've tried accessing. I, too, will be cashing out of DGB once I can access my funds.
I could host a site for you... yes, give me your privkeys (the main reason why people use cryptos is because them, and only them are responsible for their money).
Phone wallet... Phones will never be secure, for more info google "the fappenning".
