In my view, it's better to save money than invest it. Saving is a safe way, but investing has a lot of risks.
But unless you are earning a lot of money your savings are not going to be enough to change your life, you need to invest that money somewhere or when you reach retirement age you will have to live only with your savings and most of the time that is not going to be enough.
There is no person that become rich because of his savings, all of the people who save money and who got money needs a lot of things to do in order to become rich, they need to try different things like investment that will result for that person to have a passive income and it will make his life better because the expenses can be covered by the passive income alone.
Sorry my friend but you are very wrong really, the early adopters wich saved their coins of bitcoin had been able to cashout fortunes, if they havent sold any their coins till today, something hard to believe, they would be very rich people, as eth and much more others coins, how many people had invested and saved, waited a better day to sell their coins with ridicolous profit, just because they invested and saved the coins. Both are needed, because you can invest properly if you havent some money saved.
