According to monitoring by @ai_9684xtpa, a GMGN-related address transferred 6,100 ETH to Coinbase about 8 hours ago, worth approximately $16.38 million. Tracing back, this batch of ETH was bridged to the Ethereum mainnet from a Robinhood Chain-related address about 6 days ago, possibly representing transaction fee revenue earned by GMGN on Robinhood Chain.
