Bitcoin has the mathematical characteristics of money (durability, portability, interchangeability, scarcity, separability and identifiability), but it does not rely on physical characteristics (such as gold and silver) or the trust of the central authority (such as fiat currency).
Bitcoin provides an efficient way to transfer money over the internet and is regulated by an open and transparent decentralized network, unlike traditional fiat currencies controlled by central banks.
Bit is the unit of information in the digital world, so Bitcoin is naturally the currency of the digital world. Bitcoin is a digital currency with significant value in the real world. Therefore, Bitcoin can be used to exchange dollars, yen or any other currency in the world. Bitcoin can usually be abbreviated as "BTC".
If you decided to buy some bitcoins a few years ago when others were wondering if it was worth investing in them, then today you can already reap the benefits of that wise decision.
