You would have directly asked if journaling is beneficial in crypto trading or not because it directly conveys the message but adding a link to such a platform which is not that old and neither that famous, always raises concerns in my mind that you are just trying to give this website some link juice coming from this forum well, whatever the reason. And please don't mind if I misinterpret the whole thing.

Well, it might be possible that you have shared the link as a reference for our better understandability. Well coming back to the main query does it help us in crypto trading? I don't think the platform that you have mentioned would help you to journal in crypto trading but many other tools can be used to journal the crypto trades.

And yes, it would be of great value, just like it is valued for forex trading, it will be valued for crypto trading too. You must know that trading based on analysis either forex or crypto, no doubt both have differences but no doubt they have similarities also.
