Do not rush to buy, perhaps this is a small correction before the next price drop. I already bought Ethereum in September for $ 220. Now regret it.
You can always average your ETH investments. If you bought crypto not for the flip, but for the long term, then $220 is a good price. And like I said, average.
If you invest long-term, don't regret buying at that price, because Ethereum still has a chance to go back up, so don't despair.
but if you are a short-term trading then it's your fault why you don't do cutlose, you should see a chart and candle, so you know when to sell it
