Hi. Just a thought and sharing with you...
Premises:
- many people use with children the method "saving coins on piggy banks" to teach how important is to save money for the future...
- some companies (I found one in Brazil) that automatize the process to use your change (just rounding up the bill) and donating it for some proposal... it can be a cancer institute or a foundation that protect the turtles... it doesn´t matter for this post if you are altruistic or not... the idea is the method used...
- many people have difficulties to save money every month with a method...
Method:
- when you pay the bill, you could decide round up the amount and save these "metal coins" (just joking, cause you are probably using a credit card) as crytpo coins!
- these crypto coins will be saved, automatically, on your crypto wallet
- you could decide wich altcoins to "invest"
How much:
- a family using credit card for everything (gas station, pharmacy, sandwiches, happy hours...) would expand US$5.000 for year, wouldn´t it?
- US$5.000, let´s say for 500 different US$10 payment operations - or should we suppose U$9,90 in fact? :) We know the psychological marketing method, and all prices are finished by "US$x,99" and not "US$x.00"
- US$0,10 x 500 operations = US$50
- U$50/year in 10 years = US$500
- supposing 100% of appreciation of your altcoin each year - not an absurd - we could have = US$102,350.00
Plotting:

Conclusion:
- with US$500, US$50 by year, we could save "in the pig" something like US$100k.
- or at least, teach our children Economy and save ZERO :)
- but just using "coins", someones dropped on streets or forgotten under the sofa
Be safe.
