According to @ai_9684xtpa, a 2015-era ETH holder has taken profits by selling 5,125 ETH (about 20.13 million USD) via on-chain disposals and exchange deposits since Aug 2, and a total of 14,639.2 ETH (about 34.65 million USD) over nearly four months, indicating material supply hitting the market (source: @ai_9684xtpa). According to @ai_9684xtpa, the coins were originally acquired in August 2015 via ShapeShift and Poloniex at roughly 1.33 USD and recent sales occurred around 4,616 USD, implying roughly a 3,500x return, highlighting OG wallet distribution near current prices (source: @ai_9684xtpa). Such transfers to exchanges are commonly interpreted as potential sell-side pressure, and monitoring ETH Exchange Netflow and large holder flows is a standard trading approach to gauge near-term supply, per CryptoQuant (source: CryptoQuant).
