Bitcoin worked as the standard currency. There would not be enough coin to go around for each individual. Currency cannot be printed further once it reaches its limit to grow the economy , the government cannot aid in financial crisis in the same way that it can with the real dollar.
Bitcoin can't be a bubble, because it's just a ledger of transactions and a collection of nodes securely maintaining that ledger. There are no dollars and cents stored in that ledger, only Satoshi amounts.
