Blockchain monitoring platform OnchainLens reported on April 20 that a major OTC whale address (0xFB7) deposited 1,000 cbBTC into Coinbase. The transaction, valued at approximately $74.02 million, netted the whale a realized profit of about $1.97 million.
Whale Portfolio Snapshot
As of the latest data, the address continues to hold 2,000 cbBTC (worth ~$149.59 million) and 133,203 ETH (worth ~316.29 million), bringing total crypto assets to over $466 million. The deposited 1,000 cbBTC represents one-third of the address's total cbBTC holdings, indicating a partial profit-taking strategy.
Understanding cbBTC and OTC Moves
cbBTC is an ERC-20 token issued by Coinbase, 1:1 backed by Bitcoin held in Coinbase custody. By conducting large transfers via OTC (over-the-counter) channels, the whale minimized market impact and slippage. The $1.97 million profit on the $74.02 million deposit translates to a ~2.66% return, suggesting the whale's cost basis is below current market prices.
Notably, the address's ETH holdings are nearly double the value of its cbBTC position, revealing a balanced Bitcoin-Ethereum strategy. No other significant transfers were detected around April 20, reinforcing that this transaction was a focused profit-taking event.
Market Reaction
Following the news, cbBTC price dipped 0.60% and ETH fell 0.58%, signaling a muted immediate response. Analysts note that while whale transfers to exchanges often precede selling pressure, the relatively modest profit relative to total holdings suggest limited short-term volatility. Investors should monitor this address for further activity.
