It is good that you remain calm and dont panic during coin corrections and other unforeseen events that may happen, however it is good to always be on watch. Study the coin before you invest your money in it. This is what i have learned. For example there are cryptocurrencies that top the list with low price just because the quantity in the market is very high and the market capitalisation they hold is high. These may change slightly in value but the overall market cap varies a lot due to there large numbers. But they have a very strong hold in the market.

Best of luck to you for your investments
