For those of you who really want to hold your own funds (and get rid of centralized entity) the first thing to do is to make sure you hold your own private keys.
As you well know « not your keys, not you coins ». For exemple, if you’re using a Ledger or a Trezor; how would you access your funds if the screen or buttons no longer worked?

Let’s see what the seedphrase is and why it’s an important piece of your security puzzle.

Your wallet recovery phrase can go by many names: Secret Recovery Phrase, Mnemonic, Seedphrase… All these termes refer to the same concept. A sequence of words (from 12 to 24) which, if entered in the right order will give you access to your wallet from any device.

More technically, it is a human-readable version of the entropy used to generate your private keys. Originally, entropy is just a large sequence of numbers which is not easy to remember for a human being. A seedphrase is the translation of this sequence of numbers into several words that you can remember.

This transcription was made possible by the adoption of the Bitcoin Improvement Proposal 39 (BIP-39) in 2013. Since then, 2048 words from the english dictionnary can be used to translate the entropy into a recovery phrase.

And because this sequence of 12 or 24 is something a human being can easily remember, some people choose to be their own backup by remembering their seedphrase by heart. A commendable method, but not one that can survive all life’s accidents.

Each time you set up a new wallet you’ll be asked to memorize or retain your recovery phrase aka seedphrase.

As mentioned above, this sequence of words is the only thing that will enable you to regain access to your funds if you lose access to your device and need to reset your wallet. Be particularly vigilant in keeping your seedphrase. The crypto world is full of inverstors who have permanently lost acess to their funds because they didn’t take care to carefully write down their seedphrases.

That being said, it’s natural that your reflections should go through a relatively lentghy process before you choose the best option for you. You must choose was suits best your personnal needs. By definition, the best storage method should be simple, secure and cheap, just like Seedkeeper🔗.

On the Internet, you’ll find several methods of storing recovery phrases:

• The piece of paper
  • Some investors write down their seedphrase on a simple piece of paper. Yes, this is simple and cheap but not very secure. They could lost the paper, or even destroy it by accident. Sun, water and even dogs are threats to this storage method. We do not recommend to store your seedphrase on a non-durable medium.

• The steel plate
  • On the other hand, some investors write their seedphrases on sturdier media, such as steel plates that resist heat and cannot be destroyed as easily as a simple sheet of paper. However, while this method has the advantage of durability, it is not without its drawbacks. Transportability and discretion are among them. The question of cost also arises, as such a solution can cost from 50 to 100 euros depending on the size and quality of the metal plate chosen to inscribe the backup.
