From a security point of view for Bitcoin funds, the cold wallet is always recommended, the Exchanges are also safe in some ways, there will always be vulnerabilities, for the issue in general, cryptocurrencies or bitcoin in this case it turns out to be Very safe at the moment in countries with high inflation and with everything that has triggered in China by the epidemic makes people rely more on Bitcoin as a safe haven.
Its definitely a safe haven when the alternative is the bolivar or the petro. One is the fiat with the world's worst inflation and the other is a "crypto" so centralized it makes ripple look tame, also managed by the very same people that induced the hyperinflation and are giving it the treatment. Sure some people are (somehow) simply getting US dollars or Euros, and the gov now wants to tax them 25%, so its back to "parallel" market fees again... Yes they also want to tax that to bitcoin and anything else non petro. Its their "way" of stimulating petro use, by intimidation or force (yet another reason to dislike gov made altcoins). Some people seem to forget it was their own gov that made and control their fiat in the first place...
Bitcoin and others are instant. Getting foreign currency? Not so much. Storing them in a cold wallet (a paper with seed words) is far safer than using a bank that can be seized by the gov at any time, because they can and they have the guns and you don't.
Of course this also means you have to be careful using or exchanging Bitcoin, as those are the weak points which is not truly bitcoin's fault but the fact that not everyone is a directly accepting it yet. If people here used bitcoins the way they are now using foreign currencies, a new world would open. But people are hard to change.
