In my opinion, BTC compared to traditional money, the cryptocurrency has many features, financial freedom, no one controls, in addition, it can be invested for a long time to generate profits. Traditional money is left to lose value for a long time.
Also, bitcoin have low transaction fees, it very secure. It impossible for someone to have access to your wallet without the private keys. Bitcoin can be transferred to anyone in the world, it has no boundary. However, traditional money also have it own role to play, although, traditional money is been controlled by the government, they control how much money is printed.
