According to Cointelegraph:
Steve Wozniak: Bitcoin Is The Only Digital GoldOnly Bitcoin is pure digital gold
and I totally buy into that. All the others tend to give up some of the aspects of Bitcoin. For example, being totally decentralized and having no central control. That's the first one they have to give up to try to have a business model.I strongly belive in this point that Mr. Wozniak raised that, altcoins must give up chasing bitcoin and showing some aspects of bitcoin to create their own identity. Most of the altcoins try to copy bitcoin and remain as a failed one. Only altcoins with radically different structure are the successful ones. Also we can't really ignore the fact that bitcoin indeed shows some similar characteristics of gold. So saying bitcoin as a digital gold is not an exaggeration.
There are only three questions come to my mind after checking this article:
- when 20k?
- when Moon?
- when Lambo?

Lol! We all are waiting for the answers!
