Yes, many people doubt that the level of success is actually determined by large capital, but what I try to maintain myself in is to be consistent in investing so that even small amounts of Bitcoin are accumulated in the portfolio.
It's a thinking style of losers as if they can not succeed with small capital, how would they succeed with bigger capital?
It's impossible as managing a small capital is more easily and less stressful than managing a big capital. With same strategy, you would feel more comfortable with a small capital rather than with a big capital. In other word, to succeed with a big capital, you must start and gain success with a small capital for a long time. It gives you precious experience and sharpens your management skills so that you will have higher chance of succeed with bigger capital.
If anyone says, "Give me a big capital, I can succeed with it". It's dangerous calling and smart as well as careful people will never give anyone a big capital with that promise without any evidence of success from previous capital management of either small or big capital.
Your comment is very confusing. Because investing with large capital will be under a lot of pressure. What you mean is trading. An investor can invest with any amount of money and will continue to buy continuously until they accumulate enough Bitcoin in their portfolio. What you mean is trading is not investing
