Solana (SOL) has quickly become a leading blockchain thanks to lightning-fast speeds, low fees, and the innovative Proof-of-History consensus. But in the fast-moving crypto sector, rivals are emerging that could achieve even greater growth in the coming years.

Here are 5 cryptocurrencies to watch that have the technology and real-world use cases to potentially challenge Solana's dominance by 2024:

Cardano (ADA)
With a strong focus on security, scalability, and sustainability, Cardano continues to make strides with upgrades like Mithril. And with crypto regulation on the horizon, its peer-reviewed academic approach could give it an advantage for mainstream adoption.

Polygon (MATIC)
Polygon is quickly becoming the go-to layer-2 scaling solution to the high Ethereum gas fees problem. As more developers build projects on Polygon and its native token replaces MATIC, its role could dramatically expand by 2024.

Fetch.AI (FET)
At the intersection of AI and crypto, Fetch.AI aims to power autonomous machine learning-based digital economies. As AI and crypto converge, and Fetch rolls out updates like its new wallet, it could be a breakout by 2024.

SingularityNET (AGIX)
SingularityNET operates an AI marketplace where users can exchange services and algorithms. With AI's growth showing no signs of slowing, its AGIX token could surge if the project continues gaining traction.

Avalanche (AVAX)
With high throughput and a secure protocol, Avalanche has quickly become a go-to for DeFi. If the booming DeFi space continues expanding, the versatile blockchain’s native token could see major upside.

Final Takeaway
In the dynamic crypto space, unseating established players like Solana is an ever-present possibility if the technology is right. Keep an eye on projects making key advances in scalability, functionality, and real-world use cases -- like these 5 contenders -- that could reap big rewards by 2024.

Of course, every investment carries risk. So do your own research before buying any crypto asset.
