It seems to me that psychology will change, people will stop looking at Bitcoin because it lacks a lot of features that other crypto-currencies (altcoins) have. These features are as follows
- Lightning fast confirmations, ie transaction speeds. ie www.bitshares.org www.dash.org
- User Issued Assets - Asset markets where people can make businesses. ie www.bitshares.org
- Smart Contracts - Businesses incorporated into the blockchain. ie www.ethereum.org, www.digix.io/
- Currency Trading or Holding. ie www.bitshares.org www.ripple.com
- Innovative Uses ie www.steemit.com
Bitcoin has none of these features and to get these features it will have to have HUGE movement of players who hold Bitcoin to authorize any of these features. If Bitcoin cant even decide on making the blocksize bigger so their network doesnt just slow down and collapse, how will they
Furthermore, Bitcoin is still looked at as relatively new. Articles are always coming out saying how relatively new the invention of Bitcoin is. What happens when this idea changes and it becomes old.
Just my 2 cents
