Agree with the OP, in this digital age we are living in, we can't leave things to chance...
We need to have contingency plans to avoid being stranded should a crisis come, like is the case with turkey & syria..
and fortunately, cryptocurrencies are the answer to all this which should be an eye opener to all, just unfortunate it had to happen in a way that disrupts people's lives.
How can be the cryptocurrency to be the answer to all if you are living in a country where cryptocurrency is banned? I am sure people who are living in a country where cryptocurrency is ban don't have any choice but to avoid holding it because they will be charge of something illegal if they are caught holding the forbidden thing.
I think holding cryptocurrency is good for those who are living in a crypto-friendly country but not in the hostile one. I believe the advantage of holding Bitcoin is dependent on how the person's country react about Bitcoin.
Bitcoin is the best alternative way to save money, with Bitcoin you have control over your savings because it's your wallet and your key and you are your banks!
In such a scenario, bitcoin isn't a bad choice, the only downside of it is that your financial position isn't really protected from volatility and times of a bearish market but still remains a better option than keeping money in fiat which becomes inaccessible when infrastructure is destroyed by nature etc.
Isn't cryptocurrency on a wallet can't be accessible if your password and private key are destroyed by nature?
