That's why it must be relevant with a reasonable calculation of the choice. For example, choosing Bitcoin, even though the price can change at any time beyond predictions, incorporating the calculation concept as meant by the OP can make sense if the calculation of the profit percentage is greater if you set large capital for a certain period of time. If, for example, today the price starts to decline, then in a matter of days the price movement increases by up to 4%, the profits will be large compared to people who set small capital when buying Bitcoin.
