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. The value of one Bitcoin is bigger than some currencies around the world. Bitcoin will someday become the crude oil of some people and firms in the world. It will surely boom and everyone will scramble for it and at that time the scarcity of the Bitcoin will make it have more value than the real money. Save up your coins and hit the jackpot.
I'm still waiting for most companies around the world to accept BTC as a payment method. Unfortunately, this probably won't happen.
It won't happen due the same reason why gold isn't accepted as a payment method. It's just too valuable and there's a constant expectation that the value will keep raising(or just fiat money will keep losing value). That's the problem for deflationary assets. Nobody wants to use them as a payment method. The people just prefer to buy them and accumulate more and more, waiting for a higher price in the future.
What the hell is "real money"? I know the definition of money, but the term "real money" seems like nonsense to me. Legal tender money are the real money, because the government has decided that they are real, but in reality, paper money were just a derivative of gold and silver.
