To apply ETF capital flow analysis to DeFi or NFT, track capital inflows/outflows from funds, liquidity pools, staking vaults or ETF-like derivatives in the space, analyze capital changes over time, compare them to price movements/TVL growth, and identify causal relationships between capital flow behavior and major market corrections.

You can apply the principles of ETF capital flow analysis to DeFi/NFT by identifying market capital, noting the inflow/outflow movements of pools/funds/vaults, and comparing the impact on price, TVL or volume, thereby predicting major fluctuations to optimize investment decisions.
