Today, many popular cryptocurrencies have declined, which can make them attractive investment opportunities. For example:

1. Polkadot (DOT): Its price has dropped significantly today, but it still holds great potential due to its widespread use in developing decentralized applications.

2. Algorand (ALGO): It has also declined by around 10%, and is known for its speed and efficiency in operations.

3. Arbitrum (ARB): It has seen a decline of around 11% today, and is known for its significant role in improving the second layer operations of the Ethereum network.

Before investing, make sure to conduct a thorough analysis and consult a financial expert if necessary. Cryptocurrencies are volatile, and therefore, require a well-thought-out strategy.
