Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. Thereâs another optionâsecure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secureâlike Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
What Is Bitcoin?
Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoinâs creator, Satoshi Nakamoto, originally described the need for âan electronic payment system based on cryptographic proof instead of trust.â Each and every Bitcoin transaction thatâs ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. Thatâs by design: Core to their decentralized nature, Bitcoins arenât backed by the government or any issuing institution, and thereâs nothing to guarantee their value besides the proof baked in the heart of the system. âThe reason why itâs worth money is simply because we, as people, decided it has valueâsame as gold,â says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
