When big boys enter the picture, the rule has changed. Bitcoin then becoming a fprm of investments, and no longer the original vision of satoshi, iguess its really inevitable, specially during the 2016-2017 when it peaked at around$20,000. It become a speculative asset, and others tske that as a opportunity, trying to make quick bucks, or even putting thier whole life-savings hoping to become rich.
Yes actually everyone is investing in Bitcoins for making profit mainly. But there are some systems by which you can make profit like you can do short time investment or long term investment or the most I prefer is that mining because it needs one time investment and if the cost of electricity is low in your area or you are using any other power source then you can make a lot of profit.
