Blockchain and Bitcoin are not synonymous.

Blockchain is not a revolutionary technology.

Bitcoin is the revolutionary technology.

From my personal experience, anyone who constantly says the word “blockchain” claiming it is a “revolutionary technology” either has no clue what they are talking about, or they are trying to sell you something, like their “better alternative” crypto.

In reality, a “blockchain” is simply an expensive database.

Just be skeptical around anyone constantly using this 'buzzword.'
