The cryptocurrency market has seen a significant increase in trading activity this week, following the Fed's decision to maintain interest rates. Amid the broad price increase, on-chain data has revealed whale accumulation in several important altcoins.
Below are the top altcoins that crypto whales have purchased during the second week of May.
Ethereum (ETH)
Top altcoin ETH has emerged as one of the assets that crypto whales have focused on this week. The altcoin has reclaimed the $2,000 level after the US Federal Reserve took a moderate stance and the successful deployment of the Pectra upgrade two days ago.
These factors have helped restore upward momentum, and ETH whales are taking advantage of the opportunity. According to IntoTheBlock, the net flow of large investors for this coin has increased by 374% over the past seven days.

A large investor refers to an address controlling over 0.1% of a asset's circulating supply. Their net flow measures the balance between coins flowing in and out of these wallets.
The increase in net flow indicates growing whale accumulation, a potentially bullish signal that could encourage smaller investors to follow suit.
In the case of ETH, the recent increase in large investors' net flow suggests growing investor confidence, which could help stabilize the price above $2,000 in the short term.
ApeCoin (APE)
APE is another altcoin that whales have added to their portfolios this week. At the time of writing, the altcoin was trading at $0.61, up 13% over the past seven days.
Whale addresses holding between 10,000 and 100,000 tokens have purchased 640,000 APE during that period.

This group of APE investors currently holds 30.94 million tokens, the highest level recorded since November 2022. The increase in holdings suggests new confidence and growing interest in APE, signaling that large investors are positioning for potential price appreciation.
Polygon (POL)
Previously known as MATIC, POL is another token in whales' sights this week. According to Santiment, wallet addresses holding between 1 million and 10 million tokens have purchased 3.24 million POL over the past seven days.

This group of POL investors currently holds 308.34 million tokens. If whale accumulation continues, POL may extend its current price increase in the short term.
