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.
In fact, money is the main power in the present time, without money there is no value at present. Now it is important to have a good source of income before saving or investing money. However, I am not in favor of saving money, because if you save money, the value of money will start decreasing day by day due to inflation. So investing in Bitcoin is a good idea to benefit financially in the future, but some people want to get rich quickly by investing in Bitcoin, which is a wrong idea, to benefit from investing in Bitcoin, you have to plan for the long term. Now Bitcoin is a volatile currency, so the price of Bitcoin will not only increase, it is natural that the price of Bitcoin will decrease and increase, but Bitcoin has good potential in the future, so you have to be able to hold Bitcoin with risk in any situation.
