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 losing better opportunity. But there comes a time that dump took a long time so its difficult 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, remains in top 10 so its price may be difficult to recover.
