They say that Ukrainians can spot a foreigner from a kilometre away, but you shouldn’t worry about this alone making you the target of criminal behaviour. Kyiv is in fact a rather safe place. As in most cities, flashing large amounts of money could cause trouble. Wallets are known to disappear in public transport crowds, so hands in pockets at all times. Being very drunk and/or loud on the street is always a good way to attract unwanted attention, sometimes from the police. By the way, it’s a good idea for foreigners to carry at least a copy of their passport and visa with them at all times.
