Trading should be part time job and notva career because I see 5000 dollars still small for a new trader to start with in a volatile market, because in the long run, you might lose that funds. This means that to be successful in trading you must be rich to start trading. There is no guarantee that you will nake profit in trading and losses are inevitable no matter how professional you are in trading. It will be nice for me to invest $5000 in bitcoin and simply hodki than risking it in trading with a lot of stress and emotional drama.
Mate Holding $5000 on a form of short or Long term investment is the same on trading with $5000 except you are on a future or margin options with leverages. For example, if A buy Bitcoin at $94000, and decided to hold his/her positions till a favorable price renge, it is reasonable to see Mr B trading with $5000, buys bitcoin at $94000 and sell at $98000 or less. The worst case scenario for both party is similar or even the same.
Now, Mr A, may plan to hold for three years whether Price goes up or down, but Mr B may also decide to sale with a little profit margin, or hold his position, come back to sell once prices rises to certain price level to buy again when it goes dip.
In a nutshell, except you are on future or margin options, Holding or trading with $5000 has no economic differences in my opinion.
