A growing number of people are voicing their concerns about storing seed phrases on encrypted SD cards. As discussions heat up, many question the trustworthiness of digital solutions for critical cryptocurrency information.

Understanding the Controversy

Seed phrases protect access to cryptocurrency wallets. Traditionally, they were penned on paper. The shift towards using encrypted SD cards has stirred strong opinions, especially among those wary of long-term reliability.

Concerns Over Storage Methods

  1. Corruption Dangers: Many commenters have pointed to the dangers of SD cards, particularly their susceptibility to corruption. One noted, "Based on how many times I have had an SD card go corrupt, I wouldn't make this your only method to secure your assets."

  2. Encryption Trust Issues: A lack of confidence in encryption technology was echoed throughout the conversation. One commenter remarked, "If you trust the device to encrypt and decrypt, I guess you could store them wherever digitally."

  3. Backup Strategies: A noteworthy theme emerged around redundancy. Suggestions include making multiple encrypted backups using various methods, like employing PGP encryption and storing them on multiple flash drives. As one advised, "Make a triple backup for redundancy."

Diverging Perspectives in the Community

Some raised valid points about the flexibility of digital storage, with one individual stating, "The benefit is that you can have as many backups as you want since itโ€™s encrypted anyway."

"Just write down the phrase in multiple safe spots of your choice."
