Remaining calm is always the best thing you can do. The past has told us that most people who haven't sold their coins have made decent profits by just holding onto them.
I'd definitely by bitcoin at a drop, not sure about the top 10 though as they might suffer harder than btc and a few of them (usdc and doge) might be bad for long term holding.
Yes that is true. Because panic selling is mostly the reason of losing better opportunity. But there comes a time that dump took a long time so its difficult to remain calm so I think we also need to have patience. By realizing what happened in the past that holding is better, holding will not be possible if we do not have patience.
I also agree to buy bitcoins as well as eth rather other coins in top 10 because we can't tell some coins in top 10, do not remains in top 10 so its price may be difficult to recover.
Well if we look at it, the fact that there is panic is one of the strategies that have always been used in speculative markets, there are certain emotions for everything, and since the 1800-1900s there have always been these emotions given or unfounded by News, or events that arouse many feelings, is currently different but they resemble those realities, that is why many strategies of those times still remain intact but with current tools such as social networks, news, among others. Although diversifying is a great option, you should not leave everything in crypto, it is good to have investments in real estate, gold, stock market.
