it seems big investment firm are mostly accumulate eth as their investment since it's just as great as BTC, moreover ETH is always the trend setter for most of the altcoin so it make sense that ETH never gonna devalue that much and becomes worthless somehow.
regardless eth already went through various cycle of cryptocurrency even from the very beginning so ETH gonna stay for long I guess even if it's losing most of its value from the waves of correction alongside btc.
