Would btc be liquid ? How would you even send and receive even if you do own the private keys to your coin?
I am aware virtually all other aspects of our lives would be fucked properly more than likely before btc even comes to our mind if this were to happen (unless you were disproportionately invested i.e. majority of your portfolio is crypto). Still It's interesting to consider whether bitcoin really is comparable to gold in this sense - if the world really goes to shit btc aint helping noone. COVID showed us how fragile civilisation is it wouldn't take much...
To be honost with everything becoming digital these days and every aspect of our lives has become related to internet, it has become impossible to live without it, and if the internet in its entierty goes down the whole world goes into chaos, so if you are conserned about if bitcoin will survive without internet than there are far more things and systems that you need to worry about going down and not surviving, and for that reason i don't think that we will see it going down any time soon, which means bitcoin is going to be here for a while.
