The investor may not be happier than the profit after investing. 
From the way 2024 has started, we can imagine that 2024 is going to be good for the Bitcoin market compared to 2023, so now we should pay more attention to investing instead of saving money unnecessarily or keeping cash for ourselves and spending that money. I invested regularly from now on, maybe by the end of 2024 we will see the Bitcoin market double from the current level, but the investment will be ours.
