The value of Bitcoin cannot be over emphasized. The coin is one of the most valued asset right now in human history. Some people prefer saving up their coins than saving real money.
bitcoin is the real money. i guess what you meant was that some people prefer investing in a valuable and reliable asset like bitcoin or converting their fiat to bitcoin than letting inflation eat up its value in the bank .The value of one Bitcoin is bigger than some currencies around the world.
no currency in the world can equate with bitcoin even in the next 100 years to come. i think you dont know the actual price of 1 bitcoin perhaps . 
even the Kuwaiti Dinar which is leading with 1(KWD) = $3.12 as the currency with highest value is not even a match for bitcoin.
