I did the math, selling it in Cryptopia and buying again from Bittrex, and I lose about 9% without counting the transaction fees. I could go this path: ARK > BTC > LTC (low tx fee) > BTC > ARK and I'd lose about 10% of my current holding... I don't think it's worth it. I'll keep spamming Cryptopia... I was waiting patiently over a month, that's too much of a good faith from my part.
LUCKY !!! I managed to ride today's waves and by doing ARK>BTC>LTC>BTC>ARK I managed to get 51.43 ARK from Cryptopia to 49.87 ARK in Bittrex (and now to my wallet). That's only a 3% loss so I'm fine with it, I would be losing 1% every month anyway because of no voting stake.
NEO is a decent intermediary option, too, since it has no tx fees (unless it's in maintenance on Cryptopia too--haven't logged in over there for a while).
