For me it is better to save money for an emergency matter but in contrary it is better to invest it for your future so it will grow when time fly by

It's not a contrary for me because you can do both when you have enough savings, of course we save for our future but that does not only be intended for emergency situation only, otherwise we are not aiming to grow our savings. Some people are saving in the bank as they feel safe with their money and they think the interest is good enough but they didn't realize there is a better way to increase their money and that is by investing, and now bitcoin is the best investment IMO.
