If you want to hold on to a currency that has tripled, quintupled, or even 20 times, you need to think deeply from at least the following three dimensions:

1. First, understand how long it took the historical benchmark currency to achieve these gains, which is an important basis for judging the cycle.

2. Secondly, analyze how long the maximum retracement and consolidation of the benchmark currency lasted during the rise, which will help you predict the future volatility range.

3. Finally, observe the price pattern under the EMA framework to understand the important technical signals and support levels in the trend.

In a nutshell, this requires some calculations.
