You are absolutely right that long-term holders get a bigger profit than short-term traders as it is so difficult to guess where the market will go as there are too many factors that can influence on market. Personally I follow the strategy of buying almost every month some Bitcoin and other solid crypto currencies, it is my monthly investment.
You could say it because you are doing it and had seen the results but these people are in short-term traders might be doing good as well more than you. Maybe you should also have to tried becoming a trader and to see what is really happening.
It could really hard to say what is more profiting and which is not it is because we don't have the same expertise in life. Besides, holders and traders are two different situations. Well, some can justify that trading is profiting and some could say long-term holders give them the best results. It is exactly two different stories and have also different results depending on how we deal with it.
More on your own personal understanding and what kind of investment you are desiring to proceed.
Long-term holders can maximize their profits and can earn really huge when the strong bull start to pump back and deliver the target profits,
while with short-term trader, they can earn small each trade and when you add everything if they've got more winning trades than losing one,
they are also gaining decent benefits
