I'm staying away from this one.
Yes, everybody should. While not a complete scam, and I was (after one week) able to get my coins out of it, it is extremely unprofessional and a royal pain in the ass, starting with the hugest fees for every move (withdraw, trade, seems that even looking at your balance incurs a fee), to absolutely stupid and excessive authorization and verification, to overall shady practices of blocking accounts.
I thought other exchanges were bad, but this one here sets a new high standard of crappy.
