If he and you start at the same time as time and Bitcoin amount and holding rate, I think his and your success rate will be the same.
It's that simple, I found the answer during my time with Bitcoin.
This is under ideal situation which rarely happens. Everyone have his calling, his approach and indeed his uniqueness. It is practically impossible to see two people start off with the same amount of Bitcoin, same day of buy and hold in the same manner. Most likely one would have sold while one would have added more Bitcoin. These things are personal and the moment we try to copy others or become envious of them, then we are set to sacrifice our peace of mind.
Examples that make people equally successful in becoming Bitcoin investors. The difference that cannot be the same in practice lies in the situation of being patient.
You can create an experiment to test that achieving success as a Bitcoin investor will be the same as I said before.
It has been abundantly stressed that we should start with such amount that will not make us to panic, an amount we can comfortably set aside without it affecting our basic needs. This is the only way to HODL Bitcoin. Many people who ignore this simple rule have to sell their Bitcoin when they did not plan to just to settle personal needs.
Because Bitcoin investment is not done under compelling circumstances. There are basic needs that must be prioritized apart from investment needs. Therefore, whoever is consistent with their financial management will have maximum results.
