This is one of the most significant advantages of Bitcoin over fiat currencies: if you keep your fiat for an extended period of time, it will most likely lose value due to inflation, or the same amount you keep may not be enough to purchase whatever you want at the time you keep the money, whereas investing in Bitcoin will almost certainly yield a profit.

Even though the blockchain is open and visible, sending Bitcoin can be anonymous; no one will know the specific identity of the sender, whereas transferring money is not, which means Bitcoin provides security.
