With current market I'd be fixated on BTC dominance and see if there's something big going to happen.
As of now it seems inflow going to ethereum heavily, possibly because people sees it as hugely underrated and try to position themselves.
I'd expect the biggest altcoin that are top 10 to have good time in the future, as for the rest with micro market cap, I don't really know.
To be honest, I won't use ETH/BTC chart because as we know BTC is too strong in this cycle.
