Bitcoin was released at 2009. Since then, this is the first kidnapping probably linked to cryptocurrencies. Yeah, this is definitely a trend. Since people are publicly boasting about their crypto fortunes and kidnappers has published their demands... /s

You don't need people boasting about their crypto fortunes. As soon as you set up a Bitcoin tip jar, anyone can look directly at the blockchain to determine how much money you have - and how much you have had at any point in time and where the money went.

You can create and use as many addresses as you want - there's absolutely no reason to keep your savings on the same address as the tip jar.

Yes but everyone can see how much you received over the years. And, well, if there have been thousands of BTC passed through that tip jar, it's reasonable to assume that the organization still has control over a big amount of these funds.

Only if you use static addresses. If you're receiving thousands of BTCs, you can easily afford to write a widget that generates a new address for each donor (behind a captcha, to avoid DoS).

Perhaps the would-be theives might notice someone going through a lot of different addresses. Better to just use Monero and keep the single address for tips as no one would be able to see the address balance without a viewkey.
