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.
Generally, it is not possible to save money quickly. In the case of savings, a person must be patient and disciplined and start investing. It is not easy to make savings rapidly. Because there is no end to human needs. It is easy for those who are patient and make decisions for investment in a disciplined manner.
In the case of investment, if a person does not invest in any other platform and only invests regularly in Bitcoin, then there is a high possibility of long-term profit. If investment in Bitcoin is made gradually, it can turn into a big asset after a certain period of time.
