What makes you believe strongly that when the world comes to an end and everything is destroyed, the Internet will still be working perfectly for you to access your crypto? Instead of writing with so much emotions, pause and view things from different angles.  There are several ways to save your wealth and they all have there pros and cons. An individual is expected to weigh the options available to him, know the risks involved and go for the one that best suits his risks tolerance.

If you want to save wealth for the future and possibly gain some returns from it, watch out for those assets that are a great store of value. By this I mean, they are never affected by inflation and they still have the capacity to appreciate instead. There are quite alot of them like gold, Bitcoin, silver, real estate, land and many others that may be relevant in your country.

While I agree that crypto is a great way to save wealth, I do not agree also that it is the only way. I believe more in diversification. Split your wealth into different assets or investment choices and reduce the risks of losing them all.
