You just make me curious, where I can buy it?, and what material do you use for that?, Aluminum cans or cardboard?
Well, I ordered it on the internet and asked the seller to customize as I wished: with the black background colour, orange top and bottom, with Bitcoin logo and writing I provided him. It's made of heavy cardboard, while superior and inferior parts are made of plastic. These piggy banks are usually distributed as souvenirs on birthday parties with the sayings and themes of the respective events.
Where did this idea come from?
Did you buy it or did you make it yourself?
I was looking for physical goods which I could use to promote Bitcoin somehow to people around me. I thought about pens, keychains, mugs, shirts, headpieces, stickers... But when I saw those piggy banks I was sure they were an interesting choice, because they are totally related to finances and savings, therefore there could be an educative purpose behind them.
But I'm still thinking about another ideas to continue promoting Bitcoin. People love receiving giveaways, and this can be their front door to Bitcoin on their lives.
