Profitable earn in trading exactly depend on how much capital uses, if have small fund get difficult to earn much profitable in trading and I think all aspect has the same such as business or investment if want get high return need large capital for investing.
Its not matter with long term or short term when trading if uses small capital just taking small profitable although hold it until several years later, many long term holder have much capital with the high profit return but getting high risk if price dropping.
Yes, capital determines profit, the greater the capital, the higher the return will be, on the other hand, there is a greater minus risk, which is what must be faced, especially since crypto has high volatility.
If it is heavy in capital at once then it is necessary to accumulate if you want a long-term investment maybe this is the best method where it will increase your portfolio in the long run.
I choose investment over trading because it is too complicated to have skills.
Investing in bitcoin is more long-term you just wait patiently and don't need to panic when the market crashes because it is certain that bitcoin will return to the initial price or new ATH every cycle.
WOow I saw the market suddenly crash bitcoin down to $65K.
