Crypto Exchange Hacks and Security Statistics 2025: Trends, Hacks, and Prevention

In the high-stakes world of cryptocurrency, security has become a defining challenge. For enthusiasts and investors alike, 2025 has marked a significant year in the ongoing battle against exchange hacks. These hacks have not only caused massive financial losses but also intensified the demand for tighter, more reliable security protocols in the industry. As the digital landscape grows, the value and vulnerability of crypto assets rise, compelling exchanges to invest heavily in cutting-edge security measures to prevent a single vulnerability from leading to substantial losses.

Surge in Monthly Dapp Market Activity

• The decentralized app (dapp) market showed significant volatility in monthly transaction volumes over the past seven months.
• In August 2024, activity was relatively low at $69M.
• A noticeable uptick occurred in September 2024, with transactions reaching $114M, followed by a slight dip to $94M in October.
• The market experienced a sharp drop in November and December, plummeting to $18M and $11M, respectively — the lowest points in this period.
• A small recovery emerged in January 2025, with activity rising to $62M.
• The most remarkable surge happened in February 2025, with transaction volume skyrocketing to $1.7Bn — marking a massive spike and the highest value recorded in the chart.

This dramatic rise suggests renewed interest or a major event driving volume in the dapp ecosystem in early 2025.
