Bitcoin remained relatively flat as capital rotated into altcoins, with Santiment highlighting strong recent performance from Zcash, Uniswap and Hyperliquid. Santiment analyst Brian said the failure of the Clarity Act to pass the US Senate and the Federal Reserve’s interest rate hike increased investor fear, but Bitcoin recovered after a limited pullback and showed more resilience than traditional markets. The S&P 500 fell to its lowest level in a month after the rate decision, while Bitcoin avoided a comparable sell-off. Santiment’s on-chain data (blockchain activity and wallet data) nevertheless points to elevated short- to medium-term risk: wallets holding between 10,000 and 10 BTC sold approximately 57,600 BTC since August 5th, while smaller investors increased their holdings. Santiment said this pattern suggests large investors are selling into strength as individual investors enter after prices rise, raising the possibility of a pullback. Renewed accumulation by large wallets, described as whales and sharks, would provide a more positive market signal. Mid- and low-market-cap cryptocurrencies have outperformed Bitcoin and Ethereum, and trading volumes have risen notably among AI- and big-data-focused projects, including NEAR. Brian said those sectors should be monitored if the altcoin rally continues in the second half of September. Santiment treats Memecoin activity as an inverse market indicator because peak trading volume and speculative interest have often accompanied short-term market tops, while sharp declines in interest have sometimes appeared near market lows. Overall sentiment has fallen from strong optimism at the beginning of September to neutral levels after developments involving the Senate and the Fed. Bitcoin could rise above $80,000 again toward $85,000, Brian said, but the market may require new positive catalysts. This is not investment advice.
