Even if someone started investing $100 per week into BTC near the top of the first 2021 peak and through the second 2021 peak, and he continued to invest consistently and persistently that $100 every week for the past 3 years, he would be profitable right now since he would have had invested right around $15,700 and he would have 0.558 BTC (which would be worth around $22,320), and personally, I think that would be a great place to be for a person with that level of a discretionary/disposable budget..
With that 0.558 BTC, he can make huge profits when the Bitcoin price reaches $70k or even when it reaches $100k at the next ATH. That is a great result for someone already willing to invest in Bitcoin. With the profits he achieved, he was truly able to change his life for the better. With that profit, he could buy the things he wanted.
The problem is that only a few can consistently invest a certain amount weekly. Many people give up before they succeed in achieving their plans. They think waiting 3 years is too long and they slowly stop investing.
If he continues his investment, he could have some Bitcoins and the opportunity to make huge profits. He doesn't think what he is doing now can provide an opportunity to change his life for the better. That is a lesson for us to remain consistent in investing in Bitcoin.
