Ethereum (ETH) has come out as the top blockchain network for net capital inflows over the past month, pulling in a hefty $475 million in new funds. Fresh data from Artemis, highlighted by on-chain watcher @rovercrc, shows the platform easily outpaced all other chains, cementing its spot as a go-to backing layer for digital assets.
Arbitrum wasn’t far behind, attracting over $400 million in net inflows, making it the second most popular pick for capital during the same stretch. Other Layer 2 and sidechain setups like Polygon PoS, Base, and Unichain also saw some smaller gains, pointing to lively user activity and money moving within the broader Ethereum scaling ecosystem.

Ethereum Rakes In $475M; Arbitrum Strong as Other Chains Bleed Capital
While Ethereum and its close associates soaked up new investment, several other well-known platforms found themselves dealing with large net outflows. Berachain chalked up the biggest losses, with users pulling over $550 million from the platform. Optimism’s OP Mainnet also saw outflows topping $250 million.
Big names like Solana, Avalanche C-Chain, and Blast similarly experienced a drop in liquidity, suggesting a clear trend of investors reallocating their capital or migrating away from these networks, at least for now. Adding to that list, zkSync Era and WorldChain also posted negative net flows during this period.
TOTAL3 Altcoin Index Flashing Bullish Breakout Signals
Shifting focus to the wider market, crypto analyst Jelle (known online as @CryptoJelleNL) recently took to X to point out some encouraging action on the TOTAL3 index.
This index is a key benchmark as it measures the total market capitalization of all cryptocurrencies excluding the two giants, Bitcoin and Ethereum, giving a clearer picture of the broader altcoin space. According to Jelle, this index is showing solid technical signs of a developing bullish trend.

One key hurdle to overcome: $1.15T.
Break that, and the sky is the limit. pic.twitter.com/RkKqKsueY5

He highlighted that the TOTAL3 index recently retested a major support level down near $720 billion. This zone is significant because it previously acted as heavy resistance back in 2022.

The fact that these old resistance levels have now flipped into solid support is a classic technical indicator, suggesting there’s enough buying interest to fuel further growth and upward momentum for altcoins.
TOTAL3 Technicals: Key Support Holds
Drilling down into the chart data for the TOTAL3 index, it currently remains above its 200-week moving average—a widely respected long-term bullish indicator. Charts show the index has recently retested this crucial support area twice, and each time it was followed by a healthy rebound, which points to underlying structural strength in the altcoin market.

Looking ahead, Jelle and other analysts have pinpointed the $1.15 trillion mark as the next major hurdle for the TOTAL3 index. If the index can decisively break out above this level, the thinking is that it could open the door for a run towards the $2 trillion mark, potentially by mid-2025.

Such a move would clearly show a growing market appetite for altcoins beyond just Bitcoin and Ethereum, a sentiment backed up by these recent shifts in capital flow and strong technical setups at key support zones.
