Regarding the alt currencies with low volumes, I believe there is no point to adding new ones as there are no other strong enough coin (verified by market cap and time) than btc, ltc, nmc. But I see no point of keeping XRP and XVN, they requires additional support and are in fact dead or will be dead in near future because of their concept. At least they should be hidden from regular interface and available as option switch in settings. Also Korean fiat currency is redundant for most of the world - more fiat currency is very very good but they should be visible as option by switch in settings. If you want to have good feedback prepare survey for all registered users.
you're not alone, i'm waiting for a deposit since 10 days, 1 response from support (after 4 days) then when i replied nothing so far and still no deposit.
I've always spoken greatly of kraken but this detonation in service levels is a big concern.
