Debu vulkanik Tambora mencapai lapisan stratosfer, membentuk tabir raksasa yang menyaring sinar matahari di seluruh dunia. Akibatnya ini Sob, terjadi fenomena global yang dikenal sebagai βTahun Tanpa Musim Panasβ (1816).
Di Eropa dan Amerika Utara, salju turun di musim panas. Ladang gagal panen. Kelaparan dan kerusuhan pangan meluas. Di Tiongkok, musim hujan terganggu; di India, musim monsun terlambat datang, memicu wabah kolera mematikan yang akhirnya menjadi pandemi global.
Ironisnya ya Sob, sebagian besar masyarakat dunia kala itu tidak pernah mengetahui bahwa semua kekacauan ini berakar dari letusan satu gunung di Nusantara.

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.
How to Buy Bitcoin?
Most people buy Bitcoin via exchanges, such as Coinbase. Exchanges allow you to buy, sell and hold cryptocurrency, and setting up an account is similar to opening a brokerage accountβyouβll need to verify your identity and provide some kind of funding source, such as a bank account or debit card. Major exchanges include Coinbase, Kraken, and Gemini. You can also buy Bitcoin at a broker like Robinhood. Regardless of where you buy your Bitcoin, youβll need a digital wallet in which to store it. This might be whatβs called a hot wallet or a cold wallet. A hot wallet (also called an online wallet) is stored by an exchange or a provider in the cloud. Providers of online wallets include Exodus, Electrum and Mycelium. A cold wallet (or mobile wallet) is an offline device used to store Bitcoin and is not connected to the Internet. Some mobile wallet options include Trezor and Ledger.
