Piggy Bank

The accumulated crypto coin can only be removed by breaking the piggy bank.

The earliest known pig-shaped money containers date to the 12th century on the island of Java.

Numerous boar-shaped piggy banks have been discovered at the large archaeological site surrounding Trowulan, a village in the Indonesian province of East Java, which may have been the capital of the Majapahit Empire.

There are a number of folk etymologies for the English term "piggy bank", but in fact the expression has no clear origin. The oldest citation in the OED is from 1913 and 1902 for the variant "piggy bank". The popularity of Western piggy banks is believed to have originated in Germany, where pigs were revered as a symbol of good luck
