Three significant events shook the cryptocurrency world this week: the launch of a groundbreaking Solana ETF, signs of a potential Bitcoin reversal, and a contentious security incident involving Kraken exchange.

The debut of North America's first Solana ETF on the Toronto Stock Exchange marks a milestone for the cryptocurrency industry, offering investors a regulated way to invest in SOL. This development signals growing institutional interest in Solana and could lead to increased stability and growth.

Meanwhile, Bitcoin may be on the verge of reversing its June downtrend, despite bearish indicators. Analysts suggest a price reversal could bring stability and restore investor confidence.

In a controversial development, Kraken exchange is embroiled in a dispute with security firm CertiK over an alleged $3 million theft. Kraken claims extortion, while CertiK asserts it was a white hat operation. This incident highlights the need for clearer protocols in the crypto industry for vulnerability reports and exchange-security firm relationships
