as we all know trading is also part of bitcoin investment not only by accumulating and holding for long period of time,
It is a very big error to say that trading is part of investing in bitcoin, how does it even sound? Bitcoin investment and trading are far two different things because trading talks more about buying when the price is low and selling when the price is high while bitcoin investment has to do with buying at any price point and hodl for long term increment which will also attract profits along so you can see clearly that trading and investing in bitcoin are not talking about same thing.
I think the point your pointing out is crucial because many has the conception of comparing trading and Bitcoin investment not minding that if a woman and man is found in the same room doesn't mean they are same gender, trading and investment just as you have clarified are not the same the only relationship between their two is the profit which also differs in time because investor has to Wait and keeps buying till he meet or hit the expected rise while trader cut off with short time and always take little profit .
