Defi has been closely tracking ETH price action overall since that is what it is built on. With EIP 1559 and eth 2 coming, Defi is set to do very well. It does tend to act in multiples of ETH but it is also possible that ETH takes dominance during the run to flip BTC. But looking at the overall chart a correction after the EIP hype should lead Defi to another blow off top that might be the true blow off where Defi coins takes its place in top of the coin marketcap charts and remove some old legacy coins that are no longer relevant.
