I don't believe it will make big effects but have it is better than don't have it. It will be helpful for Bitcoin adoption even it is a small contribution.
Your try is a lesson to teach children about savings that are helpful for their life. If they work but don't make savings, they will have financial problem anytime. It's a good lesson for financial safety and reserve for emergency first and if better can help them richer.
Put a Bitcoin logo on piggy can help to make some impression on children and it might be carved into their minds. Some of them will remember a Bitcoin logo and a part of those children will have love with Bitcoin.
Better than doing nothing at all, although we could really say that adoption and recognition or simply the awareness is really that getting bigger everyday or it does really have that movement.
Making up these small steps is still commendable or something appreciable on which not all people would really be that doing this even though it might not really be that much effective but at least
we could really see its contribution even if it wasnt really that much but of course small things or big things sharing up with the same motive would surely count.
@OP, just continue on what you are doing and dont be bothered on whatever negativity you would really be able to hear up along the way. Good thing that you do have this kind of intent
on sharing up the opportunity and awareness about its existence. Not all people would really be having the courage and time on doing these type of things
which means that you are really that serious on spreading up the Bitcoin news.
