Actually investing in crypto is not a necessity because not everyone understands crypto investment and managing finances that will be used for capital later. But for me personally,I have the desire to save crypto assets for future savings. On the one hand I also have gold investments.
From my point of view, Investing is more common than people perceive in general. Investing is not only buying stocks or buying gold and hide it in one's house or something like that, cryptocurrency is just another kind of asset which one can invest on but the whole concept of investment goes very beyond if buying something for the sake of especulation.
If someone decides to go to college and ask for a loan to pay for it, then it is an investment. If someone decides to buy a car or even something smaller as a bicycle, it is also an investment.
Anything which gets translated to an improvement of our quality of life is something I would call an investment.
It is just a personal point of view though.
and since all of us are always seeking to improve our status and level of comfort within society, we are unknowingly always doing investments.
Would you tag the purchase of a better smarthphone an investment, I think I would, if that helps to agilize one's life.
