$BTC dominance is still holding fairly steadily around the 58% level on this chart, while ETH dominance is around 11% and the remaining altcoin groups have yet to show a clear breakout.

What stands out to me is that BTC's share has stayed almost flat throughout the period shown. This suggests that even though individual coins may be highly volatile, Bitcoin's relative position in the total market cap has not changed much.

For those of you following altcoin season, I think this is data worth comparing with the performance of ETH and the different altcoin groups. But a rise or fall in dominance does not automatically signal the start of altcoin season, since market cap can change due to both price and supply.

What do you think—will BTC dominance continue to hold around this level, or will we see a clear enough drop for altcoins to regain market share?
