📊 BTC & ETH Spot ETF Summary (As of March 18, 2026) ✅ Takeaway Both BTC and ETH are experiencing net inflows. BTC continued to see strong inflows centered on IBIT, while ETH closed with stronger positive gains than the previous day, as inflows from ETHA and ETHB outweighed outflows from FETH. Market Snapshot • BTC Spot ETF: +$199.4M • ETH Spot ETF: +$138.2M WATCH • BTC: We need to monitor whether the inflows from IBIT (+169.3M) continue and if they spread to other ETFs besides FBTC (+24.4M). • ETH: We need to check whether inflows from ETHA (+81.7M) and ETHB (+67.2M) are maintained, or conversely, whether outflows from FETH (-35.5M) increase further. Playbook 👉 Both are positive, but avoid chasing or leverage; limit pullbacks and splits. 👉 Tomorrow, increase response intensity once continuity of IBIT for BTC and continuity of large ETF inflows for ETH are confirmed.
