Summary
- Dogecoin contributor Mishaboar urges DOGE holders to reconsider software wallets for substantial cryptocurrency savings because private keys face greater exposure risks.
- The Coldcard exploit reportedly caused $111 million in confirmed losses, demonstrating how weaknesses in seed generation can compromise cryptocurrency wallets.
- Hardware wallets isolate private keys, while smartphone wallets remain better suited for payments, trading, smart contracts, and relatively smaller cryptocurrency holdings.
Dogecoin community contributor Mishaboar has urged DOGE holders to reconsider wallet security and avoid storing long-term savings in software wallets. His warning emphasizes how different wallet designs protect private keys and the risks users may encounter when choosing cryptocurrency storage methods.
According to Mishaboar, reliable hardware wallets keep seeds and private keys inside dedicated components isolated from internet-connected environments. Software wallets instead operate on smartphones or computers, placing sensitive information within devices exposed to applications, network connections, and operating systems.
His comments also address security concerns highlighted by the Coldcard exploit, which resulted from weaknesses affecting wallet seed generation. Galaxy Research estimates attackers stole 1,719 BTC worth approximately $111 million, making the incident 2026’s third-largest cryptocurrency hack.
Researchers estimate losses could reach $130 million because investigators have not confirmed every potentially compromised wallet. A firmware bug dating to March 2021 reportedly reduced seed randomness on some Coldcard wallets from 128 bits to around 40 bits.
Consequently, attackers could potentially brute-force vulnerable seeds without gaining physical access to affected hardware devices. Wallet draining reportedly began on July 30, demonstrating how implementation weaknesses can undermine security protections designed for cryptocurrency holders.

Mishaboar Highlights Risks Behind Software Wallets
According to Mishaboar, smartphones can include secure hardware capable of protecting sensitive information from broader system access. However, users cannot easily determine whether individual wallet developers properly use those security features when building their applications.
Moreover, software wallet security depends heavily on how developers handle private keys, seed generation, backups, updates, and recovery processes. Mishaboar identified faulty seed generation, information leaks, malicious updates, insecure backups, backdoors, and unusual derivation paths as potential vulnerabilities.
Despite those concerns, smartphone wallets can remain useful for cryptocurrency payments, trading, smart contracts, and relatively small holdings. Mishaboar argues that users should treat them as hot wallets rather than storage solutions for substantial long-term savings.
Hardware wallets also require careful evaluation because dedicated devices can still contain firmware or implementation vulnerabilities. Therefore, separating private keys from internet-connected devices reduces certain risks but cannot guarantee complete protection against every security failure.
For DOGE holders, Mishaboar’s warning emphasizes choosing storage methods based on intended usage and understanding how wallets protect sensitive information. Long-term cryptocurrency storage requires stronger safeguards than funds regularly used for payments, trading, or interacting with blockchain applications.
