the real wealth in crypto is made only by founders or holders , not by traders. even if you trade for rest of your life , you will never outperform the guy who bought bitcoin and Ethereum 5 years ago. analyze the data and don't be greedy. long term matters.
I totally disagree with your assumptions. Try to think more realistically and learn more. One thing, You can't really be sure long term holders are richer than traders, that's very subjective as short term investors may own more bitcoin than just long term holders. This only depends on your financial strength, so there is no certainty.
Long term investment is more profitable than trading, maybe I can justify this assumption. But going back to the old point, it just depends on who is doing it and how strong you are financially.
