I'm certainly hoping for a Bitcoin rally sometime this year though I also prefer alt coins. Bitcoin had the public eye for cryptos. What's really at stake is which Bitcoin will be maintained, I don't trust Bitcoin cash, gold or anything other than the original. It doesn't scale though so something has to change, the lightning network or POS side chains make the most sense.
Interestingly the opposite can be true when celebrities show interest in financial makets they tend to cause bubbly investments from people who don't learn about what they are investing in.
I believe the lightning network is Bitcoin's white knight. Once it is implemented across all platforms fees will go down and sentiment will go up.
I agree about "bubbly investments" but as far as I am concerned any kind of investments are good for the market. The only question is will you capitalize on the weak hands selling low and buying high or will you get lost in the confusion and make bad decisions as well.
