The surge in U.S. spot Bitcoin ETF inflows earlier in September signaled peak institutional interest. Between September 8–12, ETFs absorbed $2.3 billion, with daily highs reaching nearly $898 million. By September 18, inflows slowed to just $11.6 million, marking an 80 % drop.
Several factors explain why Bitcoin ETF flows slow:
- •Profit‑taking near resistance levels of $115,000–$118,000.
- •The Federal Reserve’s rate cut being priced in, removing some buying urgency.
- •Rotation into Ethereum ETFs, which gained $1 billion mid‑month.
This cooling period has shifted attention toward altcoin market rotation trends, with analysts flagging new opportunities beyond Bitcoin.
Many investors are asking what’s the best crypto to buy after Bitcoin ETF slowdown, and the answer often points to the altcoin space.
Aster’s Rapid Rise with Whale Activity
Aster has become a standout in recent trading cycles. A single whale purchase of $50 million worth of ASTER pushed the token to a new all‑time high of $2.41. That move alone made the investor the 12th largest holder, owning 0.3 % of the supply.

Why does Aster keep appearing in analysts altcoin picks?
- •Massive Whale Accumulation: Over $48 million worth of ASTER was acquired in just 24 hours, with large buys on Gate.io and Bybit.
- •Mainnet Testing hype: News of “Aster Chain” entering its testing phase, featuring sub‑second finality and a token buyback program, has stirred speculation.
- •Community Hype: DeFi circles have amplified ASTER’s move, fueling more trading volume and visibility.
This momentum positions Aster among the top altcoin rotations of 2025, with some calling it one of the top 3 altcoins to buy in this cycle.
Solana Gains Institutional Interest
Solana continues to attract attention for its ecosystem strength. Even with a small price dip, on‑chain data shows increasing altcoin market rotation trends favoring SOL. Total value locked in Solana DeFi passed $11.5 billion, up more than 10 % quarter‑over‑quarter.
Institutional signals remain strong:
- •Franklin Templeton and Galaxy Digital boosted SOL treasuries.
- •Helius Medical Technologies invested $167 million at $231 per token.
- •Major whales deployed $48 million in SOL buys within 24 hours.
The Bitcoin ETF impact on altcoins has left Solana in a unique position. While Bitcoin inflows are cooling, investors see Solana’s active developer base and strong institutional bids as signs it may feature in the best crypto rotation strategies for 2025 investors.
SOL ETF applications also add to the narrative. The SEC extended its review deadline to October 16, 2025, but many analysts see approval as increasingly likely. This development could place Solana firmly among the best altcoins to buy now amid Bitcoin ETF weakness.
