This article is full of misinformation and lies, clearly the author has an agenda against it, bitcoin can not be separated from the blockchain, that is a very basic fact, and if you try, you end with just an "intranet".

Bitcoin is backed by mathematics, open source code, cryptography and the most powerful and secure decentralized distributed computational network on the planet, orders of magnitude more powerful than google and government combined. There is a limit of 21 million bitcoins (divisible in smaller units). Dollars are not backed by gold anymore since long time ago, they are printed by the trillions out of nothing by the private institution called "Federal" Reserve.

Receive and transfer money, from cents (micropayments) to thousands:

Almost for free (a few cents fee).

Privacy (no need to expose personal information)

Securely (encrypted cryptographically)

Instantly (from seconds to a few minutes)

Open source (auditable by anybody)

Worldwide (from anywhere to anywhere on the planet).

Peer-to-peer (no intermediaries with a cut)

Public ledger (transparent, seen by everybody)

Decentralized (distributed with no single point of failure)

No chargebacks-No fraud ('push' vs' 'pull' transactions).
