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.
A lot of people go their whole lives without understanding that for the average person it takes time to build wealth and that it only comes from financial discipline. We all have our treats that we spend a little extra on because of the happiness they bring, but you need to be constantly re-evaluating your income and outgoings to make sure you are not leaking money away on unnecessary things. It's incredibly easy to rack up subscriptions that can collectively amass to thousands over the course of a year. You might only see 5 dollars here, 20 dollars there, but if you're not using them much then scrap it and sign up when you will get your money's worth again. Our lives are full of little decisions that can affect our long term freedom and even when we can retire. It's better to actively steer your finances rather than just floating along on someone else's waves.
