:)There are lots of things that could able to make bitcoin die. 1st. No one will use any cryptocurrency 2nd. There would be a new crypto that would replace bitcoin 3rd. No internet 4th. All government would ban it globally. and there are lots to mention but still we know that bitcoin wont die easily.
considering in the current situation all of things you have mentioned above looks like won't happened in the near future , people should feel fine and secure bitcoin won't die soon. but always worth to calculate everything include to anticipate this kind scenario.
also about bitcoin ban in around the world ,i don't think any institution can do that. bitcoin are decentralized.
