Money is power and for you to get that power, you need to invest,save money. You don't wake up one day and get that power, it takes a lot of financial discipline to achieve that.so I suggest you save up and buy some bitcoins for the rainy days.
Bitcoin is one thing that will not lose value rather it appreciate in value. Just invest because at old age you will not have the strength to start doing all that you were doing when young.
There's always a risk in any investment, especially with Bitcoin, which has quite volatile price movements, causing panic when there's a significant price drop. Regarding its value, I think many people still use logic, believing that every possibility carries a certain level of risk, even though we believe Bitcoin won't lose its value because we've long been familiar with and understood its price movements.
And I completely agree that the power of money can change many things in life, regardless of how someone obtains it. There's so much it can do, including investing for the future, which is one example.
