Nice article. I vividly remember the box saving method when I was a little boy. My aunt was a specialist in that.
Now to the meat of matter, I believe that piggy bank/box saving has paid its dues. It is way below par when compared to saving in crypto form.
However, it may not be wise for one to have all his savings in crypto form in case of emergency which may come when the market is heavily bearish.
I have never saved with piggy banks. I don't just like it.😊
In conclusion, I prefer saving in crypto because there are higher chances of the money doubling or even thrippling. @fokusnow
