Remember what happened in Cyprus in March 2013? The Central Bank wanted to take back uninsured deposits larger than $100,000 to help recapitalize itself, causing huge unrest in the local population. It originally wanted to take a percentage of deposits below that figure, eating directly into family savings. That can’t happen with bitcoin. Because the currency is decentralized, you own it. No central authority has control, and so a bank can’t take it away from you. For those who find their trust in the traditional banking system unravelling, that’s a big benefit.
