An Ethereum ICO participant has dumped an additional 19,000 ETH (approximately $47.54 million) over the past two days, according to data from Lookonchain. This brings the total amount of ETH sold by this participant to nearly 30,000 ETH, netting them a substantial profit of over $70 million. The participant initially purchased 150,000 ETH during the ICO at a price of $3 per ETH, for a total investment of $450,000. At the current price of $2,335 per ETH, their investment is now worth approximately $358 million. This represents a return of over 79,000%. The recent selloff by this participant has contributed to the downward pressure on the price of ETH, which has fallen by over 5% in the past week. However, it is important to note that the cryptocurrency market is highly volatile, and prices can fluctuate significantly in both directions.
