Actually in this case you should be able to change your mindset by equating trading and investment because in the end when you equate in terms of meaning then you can get a little lost in meaning so that you cannot distinguish whether it is trading or investment.
When we say hodl indirectly this will definitely refer to investment and I think it will be very naive if it is combined with the concept of trading because somehow this will be different.
Even though this is not too important for some people but I think it should be learned especially for beginners so that with that you can know what you should do and how to respond to a problem from hodl that must be done.
