If you've made your money by sending burly blokes to whoever is in your way, and buying off the rest; you might not be as put off by putting large sums into a ridiculously unstable asset to avoid some government to get their hands on them as someone who made their money through dedication and prudent investment. If they timed it wrong they would loose more by buying BTC than simply accepting the terms of the government, a prudent investor would see this. But some of the kinds of crooks that were hiding money in Cyprus would not think like this.
