It is the best asset to hold if you local currency goes -5% every day. Easy to buy (officially and not), easy to liquidate, can be used as unofficial currency for trade
Not by any stretch of the imagination. A highly volatile asset isn't suitable for storing value reliably. This is because the chances of you having to liquidate your position at a loss are very high.
Also USD and Euro are NOT great assets to hold. People only hold cash because they need it for transactions purposes.
