Cryptographic coin is very suspicious. They voting at Swisscex in every couple of seconds continually in the last 2 days. They reached 10k votes under 2 days without BTC. I tried searching for this coin, but it's a small one with almost zero information at web.
Maybe that's a scam...
They were probably using a bot to vote. Mintpal deducts loads of votes when they see anything that looks like bot voting. I'm not sure what Swisscex does about it.
I spoke with the owner and deleted from the list because they used vpn and root servers to voting. Thanks anyway:)
