USDC top 5 liquidity distribution in different public chains:
Ethereum: 25 billion
Base: 2.77 billion
Solana: 2.27 billion
Arbitrum: 1.19 billion
Aavlanche: 656 million
This reflects the choice of American funds. Base is a rising star, with the fastest growth backed by Coinbase. Solana is a US public chain, and its activity and performance are far superior to Ethereum.
Therefore, if you want to focus, in addition to Ethereum, it is enough to focus on Base and Solana.
This is also a confirmation that the memes of these two chains were the most active before.
