An Ethereum whale has realized a $7.3 million profit by selling 30,000 ETH in an over-the-counter (OTC) transaction. The sale, valued at $82.76 million, occurred just 20 minutes ago, following a recent price increase in Ethereum. This comes two weeks after the same whale purchased the 30,000 ETH for $75.39 million, highlighting the profitability of strategic trading in the current market.
