I saw something saying the guy who owned the ranchorelaxo account lost their keys, so can't take delegation away from haejin or power down. I know of other accounts with hundred or even thousands of HIVE that seem abandoned. Mind you there's some large percentage of BTC that is though to be unreachable due to lost keys.

These may still be early days for blockchain adoption and we are the pioneers. I have some less techie friends who happily use it, but they need to be aware of the security risks.
