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.
Good advice where if a person has enough money then he can invest from that money if he wants to get rich. Bitcoin is definitely a priority as an important investment to get rich. If an investment has a guarantee of profit, then it is advisable to make that investment. If you invest in Bitcoin and hold it for a long time, then you will get 100% profit from that Bitcoin investment and if it is saved for old age, then you should definitely do it. If you currently have the physical ability, it may not be there in old age, and if you do not have the mindset and ability to work, then only Bitcoin will give you the strength to move on in old age.
