The next time you want to check crypto prices, don't do it and use the time for a more important task: determine what you will do with the price information.
There is little use in knowing the insert your crypto price as long as you do not have a plan of action depending on the price.
The last time I checked Bitcoin was changing hands for around 3,500 USD and I didn't make a move. So what is the point in checking again unless I know how I would react. Before checking again I should answer the following questions:
It is very hard to think about the next boom phase when we are in a bear market for so long. However, I found it much easier to make my selling resolutions in a bear market.
Perhaps you are thinking: "I should have sold some Bitcoin when they were 10,000$". Well you can't change the past. But you can define your sales targets for the next bull run. For example: "I will sell some of my Bitcoins at 10,000$". Also write down why you now think you want to do this because chances are your thoughts are going to be very different when we reach 10k again. Then you might think "well tomorrow it will be 11'000 $ soon so I better hodl.
Now is the time to think about your selling strategy. Likewise, once we reach the next all time high you might think "I should have bought more Bitcoin when price was 3,500$". Had you taken such a note six 10 ago perhaps now you would buy.
After a bit of practice you will also find there is almost always something more important to do than checking the price again.
