Bitcoin is just like all other digital currencies; nothing new
Nearly all other digital currencies are centrally controlled. This means that:
- They can be printed at the subjective whims of the controllers
- They can be destroyed by attacking the central point of control
- Arbitrary rules can be imposed upon their users by the controllers
Being decentralized, Bitcoin solves all of these problems.
Bitcoins don’t solve any problems that fiat currency and/or gold doesn’t solve
Unlike gold, bitcoins are:
- Easy to transfer
- Easy to secure
- Easy to verify
- Easy to granulate
Unlike fiat currencies, bitcoins are:
- Predictable and limited in supply
- Not controlled by a central authority (such as The United States Federal Reserve)
Unlike electronic fiat currency systems, bitcoins are:
- Potentially anonymous
- Freeze-proof
- Faster to transfer
- Cheaper to transfer
