$BTC .D We've seen a few days where alts have outperformed $BTC, mostly led by $ETH .
But for this trend to truly change around I think we need to see a big run by a coin which creates a lot of hype.
One thing that can play into the favor of alts over time is the fact that new money will look at BTC and think: "Okay it's already $100K+, even if we go to $200K I "only" make a 2x, might as well go further down the risk curve!".
The latter is generally how alt runs are created.
But we'll need much more than a few days of outperformance to get excited for a larger altcoin run.
