Hello! We are talking about the site https://iancoleman.io/bip39/ and the creation of a mnemonic phrase. The situation is the following. I don't want to spend money on a hardware wallet. In addition, hardware wallets fail, become obsolete from a technical point of view. I want to create a Bitcoin savings wallet that is not intended for spending.
So. I'm planning to create a SEED phrase on a computer that doesn't connect to the network at all. Unfortunately, it is impossible to install anything on it, including Electrum. Otherwise, I would just create Electrum and not do it. iancoleman.io allows you to generate a phrase offline.
Has anyone used a similar method? And I'm also wondering if there is a possibility that after entering my created phrase into Electrum (for example) there will be some problems? Is there some kind of failure? Since I’m not going to enter the phrase now: the wallet is created exclusively for accumulation. Of course, the time will come for him too, and sooner or later the phrase will have to be entered. Is it possible that there is some random or special error in the iancoleman.io program (or utility) itself, which will lead to the loss of digital assets? Thank you in advance.
