A debate is spreading in the cryptocurrency industry over so-called “bunker mode,” a strategy of moving assets to new addresses to protect them as concerns grow that artificial intelligence could undermine existing cryptography. There is still no evidence that AI has broken cryptographic systems, and some warn that hasty transfers could increase security risks through mistakes or scams. Experts also say the impact would extend beyond wallets to blockchain infrastructure and consensus mechanisms.

In the crypto hardware wallet market, clarity of on-device transaction verification and asset recovery after loss are emerging as key selection criteria, beyond the number of supported coins. Cointelegraph compared major wallets by security, connectivity, usability and recovery options. Differences were notable in input experience and screen design. Wireless, wired and QR-based models offer varying trade-offs, but none guarantees safety if users approve malicious transactions or leak backups.
