Investment planning is another advice they seek, they would want to make wise investments decisions, how they should diversify their investments, how much they should allocate to each portfolio.
Traders' investment portfolio must be having more risky instruments compared to what an investor try to trade, lol.
I do see even aggressive traders do have investment portfolio but I am not sure that they plan up for long term like a typical investors do. Investment just needs your knowledge which is completely different from the skill set of a trader. You need to study all the fundamentals also for a perfect entry you need to check short term technical analysis as well. For example, to catch bitcoin below $20k level in 2023, you need to understand bitcoin's fundamental and cyclic nature here technical analysis might get you chances to average more around $20k to 25k levels.
Traders' investment might focus on short term plans but such assets are coming up with more risks. To eliminate risks, we can simply go for long term; this way bitcoin must be a the only one asset needed for both traders and investors in their portfolio.
