The crypto market could move sharply if the Federal Reserve announces a rate cut on September 17. The chances of a cut are now over 90%.
Some banks, including Standard Chartered, expect a double rate cut of 50 basis points. In the past, rate cuts have pushed altcoins higher than Bitcoin. During the last similar cut, the altcoin market cap rose 5.7%, outperforming Bitcoin by 1.3%. Here are top three altcoins to stack:
Altcoin 1: Cardano ($ADA)
Institutional holdings of $ADA have risen 300% in 2025. Large wallets have added over 210 million $ADA in the third quarter, equal to 10.3% of the total supply. The US Clarity Act, effective October 2025, recognizes $ADA as a mature blockchain. This change could lead to an $ADA ETF. Approval may trigger new retail inflows and support a strong price rally.
At the time of writing $ADA is trading at $0.87 and is down by more than 1%.
Altcoin 2: Hedera ($HBAR)
The SEC recently delayed a decision on $HBAR ETFs until November 8. Hedera is working with Swift on blockchain-based cross-border payments. It was also chosen for Wyoming’s Frontier Stable Token. These partnerships show adoption at both the state and international levels. Positive ETF news could attract more institutional investors.
$HBAR is up by more than 5% in the last seven days and is trading at $0.23.
Altcoin 3: $SEI Network ($SEI)
$SEI rose from $0.13 in March to $0.27 in July. Circle revealed it holds 6.25 million $SEI tokens, hinting institutional confidence. The upcoming $SEI Giga upgrade will increase execution speed, enable over 200,000 transactions per second, and deliver sub-400 millisecond transaction finality. This makes $SEI suitable for real-time and high-frequency applications.
$SEI is trading at $0.31 at press time.
