Bitcoin ETF inflows lift BTC as Pi Network turns bearish

Crypto exchanges surge, Bitcoin ETFs draw billions, and Pi faces bearish signals

US spot crypto venues are taking a bigger slice of the pie, even as overall centralised exchange activity cools. The spark is ETFs. They have re-routed liquidity, tightened spreads at the top end, and dragged price discovery back towards US hours. Meanwhile, Bitcoin pushed to a six-week high near $73,800, helped by steady ETF buying and a violent squeeze in short positions.

Flows did the talking. Crypto funds pulled in about $1.06 billion last week, extending a run that now looks like the longest inflow streak since October. Therefore, traders have stopped fading rallies so quickly. Instead, they are watching the daily tape of ETF creations and redemptions like it is payrolls Friday.

Exchanges ride the ETF wave

Bullish, which pitches itself as an institutional-first venue, sprang past Coinbase in spot volume last month. Volumes jumped 62% to $76 billion, giving it a 5.06% share. However, this reshuffle happened while the wider centralised exchange market slipped on muted volatility. US spot venues still grew in relevance, because ETF-related hedging, arbitrage, and custody flows tend to concentrate where dollar liquidity lives.

Binance remains the heavyweight, with roughly 22% share, yet its dominance no longer looks unshakeable. As a result, competitors are leaning harder on fee incentives, deeper liquidity programmes, and tokenised asset offerings. Meanwhile, Crypto.com pushed at the “spend it” narrative with a South Korean tie-up involving KG Inicis, aiming to let tourists pay with crypto through familiar rails.

Bitcoin leads, Ethereum follows

Bitcoin’s rally had two engines. First, spot ETF inflows came in around $180 million on the day that helped drive the latest push. Second, the market saw more than $2 billion in short liquidations, which acts like forced buying when traders get the level wrong. Therefore, upside moves have started to feel jumpier, with thinner air above key round numbers.

Corporate and “whale” positioning is also back in the conversation. Metaplanet has become a poster child for equity-linked crypto exposure, with investors treating it as a listed proxy for a growing Bitcoin stash. Meanwhile, Ether caught a bid above $2,000, with institutional plumbing expanding even as the ecosystem digests headline-grabbing Foundation sales of 5,000 ETH.

Ethereum’s institutional wrapper story continues to evolve. BlackRock’s ETHB staking ETF has leaned on Figment for staking operations, underscoring that yield is becoming part of the mainstream pitch. However, the market still treats Bitcoin as the cleanest macro trade, especially when ETF flows dominate the narrative.

Altcoins split: Pi weak, Zcash perky, XRP watched

  • Pi Network: Technical signals point lower, with traders flagging a bearish crossover and downside levels near $1.50. However, forecasts are all over the map, ranging from sub-$1 projections to calls that assume a sharp recovery from depressed levels.
  • Zcash: A reversal pattern has bulls talking about a move towards $300, although that would require sustained risk appetite.
  • XRP: Whale accumulation and higher activity are supporting the story, even as price action struggles to keep pace. Therefore, $1.50 has become a line to watch for both momentum and sentiment.
  • Solana: An ascending triangle has traders eyeing a $100 test, but it remains sensitive to broader beta swings.
  • Pepe: Rebounded about 20%, tracking the wider risk-on mood and chasing earlier-year highs.

Regulation tightens, even as some cases fade

Regulators stayed busy. Vietnam is weighing restrictions on overseas crypto trading access. Argentina moved against Polymarket after scrutiny intensified. South Korea, still cleaning up after enforcement and custody mishaps, tightened seizure rules and fined Bithumb about $24.5 million. Meanwhile, Australia is again pushing to pull crypto further under traditional financial rulebooks.

In the US, enforcement looked mixed. Some suits dropped away, including an airdrop-related case and the BitClout matter. However, the SEC is also proposing changes that would remove crypto from certain OTC reporting categories, which could reshape visibility for smaller tokens.

RWA and DeFi keep building through the noise

While headlines fixated on ETFs and enforcement, tokenised real-world assets kept chugging along. Aurum hired Nick Patel to focus on RWA initiatives. Streamex added an ex-Coinbase finance executive as it pushes tokenised gold. Meanwhile, Lido sharpened its staking approach with DVT work, reflecting a broader effort to make staking look more robust to institutions.

Not every launch is on schedule. OpenSea delayed its SEA token plans, citing softer market conditions. Therefore, the risk appetite that lifts majors still has not fully trickled down to every corner of crypto.

What traders are watching next

  • ETF flow tape: Daily creations remain the cleanest signal of institutional risk-on.
  • $73,800 area: Bitcoin’s recent peak is the nearest “prove it” level for momentum.
  • Liquidation risk: After $2 billion in short wipes, crowded positioning can flip quickly.
  • Macro catalyst: A Fed decision could either bless a $75,000 test or snuff it out.
  • Regulatory drift: Asia-Pacific rules look set to tighten, which can change exchange flows.

Key takeaways

  • US spot venues are gaining share because ETF activity concentrates liquidity and arbitrage in dollar markets.
  • Bitcoin’s rally is flow-driven and liquidation-fuelled, so breakouts may stay sharp and mean-reverting.
  • Ethereum is benefitting from staking ETF infrastructure, although Bitcoin remains the dominant macro proxy.
  • Altcoins are trading like a stock picker’s market, with Pi technicals flashing danger while others stabilise.
  • Regulation is not a single headline risk. It is a steady pressure that can quietly reroute volume.
