A geocoin is a round, uniquely numbered coin-sized object hidden in geocaches. Geocachers track and move them from cache to cache, contributing to their journey and logging online. So the option D is correct.
A geocoin is a circular, coin-sized object used in the popular outdoor recreational activity known as geocaching. Geocaching involves the use of GPS devices or mobile apps to locate hidden containers, or "geocaches," placed by participants worldwide. Geocoins are special items hidden within these caches, each bearing a unique tracking code. The primary purpose of a geocoin is to travel from one cache to another, logging its journey online as it moves from location to location.
Geocachers discover these coins in caches, noting the tracking code, and may decide to take the geocoin with them to place it in another cache. This process allows geocoins to accumulate a record of their travels, creating a fascinating narrative of their journey through various terrains and locations. The tracking codes enable geocachers to log the movements of the geocoins on geocaching websites, fostering a sense of community and shared adventure among participants.
In addition to their tracking codes, geocoins often feature unique designs, themes, or messages that reflect the personality or interests of the geocacher who released them. Geocoins contribute an element of discovery, exploration, and connection within the geocaching community, making them cherished collectibles and enhancing the overall experience of this global treasure hunt.
