On Sunday, the cryptocurrency market rebounded strongly, with Bitcoin rising 5.2% to $66,843, essentially recovering from the decline caused by the US and Israel airstrikes on Iran on Saturday. News of the death of Iran's Supreme Leader accelerated the rebound, with traders believing it could shorten the conflict. Solana surged 10.8%, leading the major tokens, while Ethereum increased 7.5% to $1,994. Despite the significant single-day gain, Bitcoin still declined 1.6% this week, highlighting the market's volatility and directional response to geopolitical news. As traditional markets reopen, the sustainability of this rally will be put to the test.
