It's difficult for people not understanding this market to find out what's a potential bottom or all time high, and that even applies to the more senior crypto enthusiasts. What today can be considered a high price, is tomorrow a very low price, and what today can be considered a low price, can be seen as a high price tomorrow. In some cases common sense will prevent you from buying at all time high levels, especially so when the all time high is as obvious as the one from last year, but it's not always that easy to spot. And yes, the best way to deal with this is to either sell in smaller fractions, or to enter the market in smaller fractions. Going all in or all out is just stupid and leads to nothing but stress....
