Ich habe mir beim ersten Einrichten bewusst Zeit genommen. Danach schätze ich besonders die Unabhängigkeit von Elektronik und die robuste Haptik. Gerade das einfache Konzept wollte ich bei einem Backup Werkzeug haben.

Für mein Sicherheitskonzept schätze ich besonders ein physisches Offline Backup für den Seed und das kleine Format für die langfristige Aufbewahrung. Passt gut zu meinem Setup.

Bei einem Backup Produkt will ich vor allem eine einfache und nachvollziehbare Lösung. Hier schätze ich das kleine Format für die langfristige Aufbewahrung und ein physisches Offline Backup für den Seed.

J'ai volontairement pris mon temps lors de la première configuration. Ensuite, j'ai surtout apprécié avoir une sauvegarde physique hors ligne de la seed et le petit format pour le stockage à long terme.
