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.
Of course, anyone that's not financially discipline will end up having nothing to fall back on at old age. Bitcoin long-term investment needs financial discipline in order for you to buy with DCA method build, grow and hodli for the future. If you are not financially disciplined, when you see a little profit, you will sell and feel that you are smart.
It's what we work down for the future that we determine our financial strength at old age which is the main reason why we most make investment our priority than spending money on consumptional things. It's easy to start up your bitcoin investment than any other business and personally, I put bitcoin first before anything.
