The crypto market is bouncing back, with Bitcoin trading above the $110K mark. But the real deal is what whales are betting on for the second half of 2025. History shows that when whales load up during weak markets, a price bounce often follows once sentiment turns around, and this time, they’ve revealed the coins they’re backing for the next big move. Here are three coins whales are stacking: Bitcoin Leading the Charge Bitcoin remains a favorite for these big players. New on-chain data from Glassnode shows that wallets holding over 1,000 Bitcoin rose by more than 3% this week, the biggest accumulation spike since early 2024. It’s a strong signal that large investors still believe Bitcoin is undervalued. For nearly a week, daily whale accumulation has exceeded 800K #ETH, pushing holdings in 1k–10k wallets to >14.3M #ETH. On June 12 alone, #Ethereum whales have added over 871K $ETH – the highest daily net inflow YTD. This scale of buying hasn't been seen since 2017. pic.twitter.com/zCMj9HX6Ft — glassnode (@glassnode) June 17, 2025 Even though Bitcoin ETFs have attracted massive funds, some long-time holders who bought at lower prices are selling around current levels. This has created a period of price churn where the market is stuck between old sellers and new buyers. At the time of writing, Bitcoin is trading above $110k and is up by more than 2%.
