Trading and investing are two completely different things but at the beginning we lump them together. And there are many people whose activities show that they are trading but they claim to be investors. How I put it, the person buys bitcoins and keeps the bitcoins for a few days when he sees that the market is positive and makes some profit then he sells his bitcoins and waits again for the market to come back. We must consider this as trading. Investing is not like that, investing is buying a coin in a long term plan and holding it for a long period of time. That is, if an investor buys Bitcoin, he cannot plan to sell the investment for a long time and must try to maintain the continuity of the investment according to his ability. If we are successful in doing this, we will be considered as an investor. But the road to long term investment is not so easy, it is much more challenging and we must accept this challenge and ensure to sustain it for a long time to achieve success.
It is not possible for one person to be a trader and investor at the same time. If any trader claims to be an investor, I would call him a hypocrite. Because a trader is very likely to be tempted. He may not have the control to hold the investment while trading.
Being a bitcoin investor doesn't mean a person can not trade as well, It's a matter of choice. But I see such choice as not a good choice expecially at the beginning of a persons journey of HODLing. It is better people concentrate on bitcoin investment and see what they get out of it in the lung run, before they can think od gambling %10 of the HODLing by trading. No doubt most folks do trading+investment simultaneously, by investing once at a go (lump sum), or DCA. and continue trading on a daily basis which doesn't stop them from investing. of course that is not what we are discussing here, but just to bring to your notice that it is possible but not encourageable.
Yes is possible but just like you said is not encouraged especially for a newbie to go into because at a point it will surely distract them, take for a example a newbie who just started Bitcoin long term investment and also trading when he start losing money in trading he will also lose his focus in long term investment and that will be the end of it.
For me I think when one is into Long term Bitcoin investment using DCA strategy he should focus in it and forget about trading because it will cause him or her distraction, one can't compare someone that is focused in Long term Bitcoin investment using the DCA strategy and someone that is into Long term Bitcoin investment using DCA strategy and also active in trading that person that is just focused in Long term Bitcoin investment using DCA strategy will do more better and become successful more than the other person.
