Interesting thoughts!
regarding other cryptos, I'm really excited about EOS, I think it will be a niche for many many dapps and companies because will have more advantages than ethereum (zero fees and speed). What do you think about EOS?
Regarding Bitcoin: My fear is that the people realize that it is slow and not scalable and the price fall. My opinion is that in long term it will lose its 1st position in the market cap.
