It is important to backup your seed phrase but some people said the backup is not good online but which is true because we have seen how hackers was able to see some people seed phrase online and steal their coins. But I have been thinking recently that how can people in countries with natural disaster be able to backup their seed phrase offline? An example is the flooding that occured in Pakistan like 2 or 3 years ago that submerged 1/3 of the country under water. Even if you backup your seed phrase offline in many locations, it is possible that kind of flood can lead to permanent loss of your offline seed phrase.
