Though I wasn't part of those who were the first adopters of Bitcoin around 2009-2019, I have witnessed price increases over the few years I have spent in the crypto space. Unlike fiat currencies that retain their value or sometimes get devalued, Bitcoin happens to be one of the few commodities that accumulate in its worth due to scarcity and increasing demand. As demand for Bitcoin increases, holders prefer to store rather than sell, contributing to more scarcity in supply.
When Bitcoin hits a new all-time high (ATH), it's good evidence of growth and value. Bitcoin keeps breaking its previous ATH over the years, especially during halving cycles. Interestingly, the ATH protocol isn't going the way it should due to the recent approval of a Bitcoin ETF. More demand for Bitcoin has been raised, thereby increasing the price of Bitcoin to a new ATH even before the halving.
Bitcoin surely has a promising future for those who capitalize and invest as much as they can.
