I think both matter, but the funding response is usually the first signal the market reacts to. A net inflow of around 1,870 BTC is not trivial, yet it's also not the kind of number that automatically changes the trend on its own. What matters more is whether that inflow keeps building over the next few days, and whether it shows up in spot volumes, perpetual funding rates and open interest. If the flow reverses quickly, most of the move was sentiment. On the implementation side, I'd watch whether these funds are actually being deployed — ETF creations, treasury purchases, exchange reserves draining — because that's the part that hits real liquidity. My personal take: short-term noise, medium-term structure. Just my two cents, not investment advice, and please verify any flow data with the official sources or exchanges.

Personally I lean toward implementation changes being the more reliable thing to track. Fund movements can be headline-driven and mean-reverting; a single day's net inflow says very little without context — you need to compare it against the recent average and against outflows elsewhere. What I actually care about is whether the money is 'sticky' — i.e. moving into custody, cold wallets, ETF holdings — versus hot money rotating through derivatives. If it's the former, it can quietly tighten available supply and matter for weeks; if it's the latter, it might be gone before you finish reading the news. The funding response tells you how leveraged traders are positioned, but it can also be a trap because crowded funding often precedes a squeeze. So my order of priority: on-chain/custody implementation first, funding reaction second, price reaction last. Not financial advice — do your own research, and treat any 24h figure as a snapshot, not a trend. It would be interesting to see what others in the community are watching.
