The past year, about ~50% of the top 50 coins have outperformed BTC. This is actually one of the highest levels we've seen since the 2021 top. I think this is due to a lot of coins having had a very bad final bull market year and generally selling off a ton already throughout 2024 & 2025. This has caused many of these to pretty much trade sideways against BTC for some time now, which is why this has trended up.(Daan Crypto Trades)
