No problem if you can not participate in ETH2 staking because you can still profit from trading, and I am sure that your chance to buy low and sell high will be wide open. Ethereum will get its time to have the bullish again, but this time, we need to be patient and not panic, especially if ethereum goes down for more. What we can do later is prepare our money to buy more ethereum if we want to buy at a low price. Otherwise, we can only wait and see the price movements.
