βTo the extent it is used I fear itβs often for illicit finance. Itβs an extremely inefficient way of conducting transactions, and the amount of energy thatβs consumed in processing those transactions is staggering,β the former Fed chairwoman said. Yellenβs comments have been cited as a reason for bitcoinβs recent losses. However, Yellenβs assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.
Telegram auto-delete message, expiring invites, and more
elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsAppβs privacy policy and now the company is adopting features that were already part of its competitorsβ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegramβs encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete wonβt remove every message though; if a message was sent before the feature was turned on, itβll stick around. Telegramβs competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
