Clabo Inc. (headquartered in Minato-ku, Tokyo; CEO: Ikuma Ueno) conducted a survey of 746 people with cryptocurrency investment experience on their awareness and implementation of security measures, particularly two-factor authentication (2FA). The survey found that only 29.4% of investors had enabled 2FA across all services they use. Although many recognize the importance of security, 43.7% admitted that they know it matters but find it troublesome, highlighting a risky tendency to prioritize short-term convenience over safety. Among investors holding less than 10,000 yen in crypto assets, roughly half were effectively unprotected, showing that complacency driven by small account balances may be increasing hacking risk. The report also explains that people in their 50s had the highest non-adoption rate across all age groups, while investors holding 5 million yen or more were more likely to implement thorough protection, revealing a clear security gap by asset size. In a cryptocurrency market governed by self-responsibility, skipping a setup process that takes only a few minutes can lead to the risk of losing all assets. The report warns users of this danger and presents essential defensive measures that all users should take. The largest group in the survey, at 44.6%, consisted of investors who had enabled 2FA on only some of their crypto-related services. This reflects a limited security mindset in which many investors believe protecting their main exchange is enough. However, attackers persistently target weak points. If even one account or service has a security gap, other assets and personal information may be exposed as well. The belief that “the important places are protected” can itself become a major vulnerability. Another 19.8% of investors had not enabled 2FA at all, while 6.2% said they did not know what two-factor authentication was. Together, these groups account for 26.0%, meaning around one in four investors is participating in the market while large
