For business time is so necessary. Most forex traders are more successful during the late US, Asian or early European trading sessions essentially 2 PM to 6 AM Eastern Time (New York), which is 7 PM to 11 AM UK time. Thats the time when some traders are going to make trade. It is so important to them.
Time is gold for traders and for those new aspiring traders whether it is with forex or crypto they need to use their time wisely.
And because we are in the crypto currency based trading, when you see a good amount of the coins that you are holding.
If you believe that you've got good profit from it, that will be good if you are going to sell if not better wait.
I don't know that there are some certain timeframe with forex traders.
