I have so many more reasons to expect this, which I might follow up on later. Long-story short though, I was bullish all the way up from the bottom to the first time it hit 8k, but since then I've been expecting altcoins to have their turn. Even as someone who's only been in since 2017, this is a very familiar cycle to me. BCH/BTC being so overdue for a rise also helps explain why and how it will be possible for altcoins to continue their surge despite the fact that bitcoin is consolidating, which seems like it hasn't happened for a couple years. I have longer-term analysis on this as well which I'd like to post links to but since I can't, I'll just say find me on twitter, steemit, or YouTube if you're interested in more.
