At what frequency? Statistically speaking, how likely do you think this is for a given account worth, say, over $100k?
This depends on the given parameters that include:
- degree of publicity by the user
- reliable access to the person (-> routines to break into)
- the actual speed and tracelessness of removing crypto
- opportunity costs like how simple it is to steal a rolex and market that
- knowledge of criminals about Steemit, crypto markets and their functionality
- the overal criminal market (number of ppl within borders per criminals among the population)
- the desperation of criminals (classic criminals, jealous friends and aquaintances or even terrorists in need for funding)
- (1) and (2) are a given for > 1k users and I would say at least two dozen whales (you, @jerrybanfield, @surfermarly, @exyle and his mom @clio etc. and all of the participants of the Steem Fest)
- (3) and (4) is what I claim to be the case and a novelty; it's the main part of my argument
- (5) and (6) are statistical questions: 1 in 1,000 is a criminal who goes extreme if necessary; 1 in 50 has enough knowledge about the crypto sphere => 1 in 50,000 is a crypto thief prepared to make house calls and according to @arcange, Steemit has around 40k users => There probably is already a user spying on you here on Steemit (maybe he even tries to befriend you and give you his scenario;-) and the US and EU are both big enough markets which also have giant holes in their border fences...
- (7) there's plenty of crazy people out there. All they need is the occasion of someone not being as vigilant as his situation demands him to be.
You're right that impulsive action is wrong, but I think the numbers give it away that there is a rational base to act and that's why my bottom line is: You and maybe 30-100 users are already in the red zone. Vigilance is important when it comes to disclosing too much about the personal life, names, faces, places, dates and so on.

Just look at the wallet of @sweetsssj: It's 350k $ worth right now and she seems to have a 2nd account from which she delegates another 750k SP to the 1st account, which makes it a total of some 3 million$ - and she's like 1,50m tall.
