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.
Definitely money is power so to be able to maintain that power we need to find way to increase our source of income. Well investing in Bitcoin is not a bad idea but you don't invest in Bitcoin and hope to become wealthy from it overnight. becoming wealthy from Bitcoin can be determined by the amount of Bitcoin you have accumulated and the decipline to HODL for a longer time without selling with a mear problem. A person that want to be wealthy needs to diversify into different asset and increase in sources of income which this income generated can be invested in Bitcoin regularly till a reasonable amount is invested and it's profit will increase overtime or in the lung run.
Money and power goes hand in hand, if you have money the next thing is to have the power and discipline to control it because nothing is constant in this world, without control you can lose both your money and influence which is your power. Bitcoin is not a physical business it is an investment that can give you returns on the long term. You don't have to depend only on Bitcoin profit to survive because it is volatile and you will hodl for long term before you can get profit, if you have more funds you can diversify into other profitable assets like gold and real estate, all of this assets combined can make you more financially stable and powerful.
