That's right storing your money through btc or cryptocurrency is the safest way to hide your money in case of war. Look at how some of the iranians transfer their money through btc in order to successfuly put it on safety. Although there are negative feedbacks against cryptocurrency during war but wise people finds it the safest option to store your money.
We cannot please people to think negative and it's a part of the game but good thing some of them manage to transfer their funds on bitcoins since this is more convenient and portable for them once their are battles happen, we should remember that the economy of the certain country who go thru war will shrink and maybe it t will be good to have an option so that if their money will be devalued they don't have to worry about since their money is safe with bitcoins.
