The advantage is that you don't necessarily have to wait for years before meeting your goal. Those who bought in bulk when it was bearish have probably reached their goal at the current $72k while those who bought a minimal amount even years back when Bitcoin was around $20k will be in profit but wouldn't have a profit anywhere close to someone that starched a good amount of Bitcoin at let's say $40k
What I'm saying is that as much as it's important to buy based on our financial capacity, it's also good to put in additional effort to starch more in our portfolio if we are interested in making a good profit from our holdings. Remember that your profit is directly proportional to how much you've starched up in your portfolio.
You know, in this day and age, even if you are not a wealthy person or earn a lot of money monthly, if you have a deep goal, for sure you will be able to save Bitcoin, even if it's just a small amount. If you do it repeatedly at the beginning, you won't feel what you are doing, but as time goes by, you will feel the high value of what you save one day.
Actually, that's how I'm starting now, little by little. I want to save Bitcoin 10 years from now because I am pretty sure that bitcoin's price value will be high when that time comes.
