Every investor's number 1 goal is making profit. I don't see why one should not think about profit or expect his investment to appreciate in value over time . The only thing is the person should not over expect the profit to come, as it can't be guaranteed or predicted when exactly you will see it, trading which you are also recommending is like gambling and requires great knowledge even as that the risk associated with it is high compared to just holding bitcoin over long period of time.
Do you think that the wealthy people are investing into bitcoin to make profit, I doubt that it's everyone that's investing for the sole purpose of making profit from their bitcoin investment. Some folks are investing into bitcoin to preserve their wealth from depreciating in value overtime since Fiat loses its purchasing power overtime and Bitcoin is a store of value overtime.
The government that are buying bitcoin or created bitcoin reserve isn't doing that for profit but to preserve the value of the State/Country funds from losing value overtime. If you put profit first, you might end up selling your bitcoin too soon when you see a drastic pump in price without accumulating enough. This is why you shouldn't put profit at the back of your mind as you are investing but focus on consistent and persistent accumulation of bitcoin for 4-10 years or more in order for you to reach your bitcoin target and don't get distracted with the profit in your bitcoin portfolio.
