According to CoinDesk, all major cryptocurrencies declined due to geopolitical tensions from Israel's attack on Iranian nuclear facilities, with BTC down 4.7% to $103.3K and ETH dropping to $2,694. Despite this, ETH has surged nearly 40% over three months, acting as a leading indicator for altcoin capital flows as investors shift focus from BTC ETFs to sectors like DeFi and AI, per Charmaine Tam of Hex Trust. MAS has banned offshore crypto exchanges like Bitget and Bybit in Singapore, a regulatory response linked to past failures of Three Arrows Capital and Terraform Labs, requiring full oversight for firms using the city-state's name.
