Cryptocurrency is The best way to invest money. Invest in bitcoin and other promising coins to earn money to have a better living and to have a freedom financially. Every people investing has only one purpose in "to earn money". But for specific goal, it depends on a every person because there are people who want to be rich through investing and other are just making money to survive for a daily living.
So you are saying the best way to invest your money is to put in on something very volatile and risky? Lol, no it isn't. You shouldn't be investing in bitcoin or any crypto currencies if you can't afford to lose it. And I don't think there is any person over here that isn't investing in crypto currencies to become rich. Of course everyone makes investments to earn and become rich eventually.

other are just making money to survive for a daily living.
Then they shouldn't be investing at all. Investing in bitcoin won't give you money to make ends meet. Based on how volatile the market is, they probably won't be able to pay their bills the next day. Invest if you are planning to hold long term.
