"Bitcoin" has two meanings:
1. Computer money - bit, as in byte, and money;
2. The hidden meaning - In the old days, gold was money. The way the average person tested to see if a coin was pure gold was to bite it. Gold is soft, and the teeth can make indentations in a pure gold coin. However, often a person accepting a gold coin as payment, didn't have to bite the coin. All he had to do was look at the number of bites on the coin to see how often the coin had changed hands, being there by authenticated. Hence, bit coin. The people, back then, who were at a disadvantage, often were the people who handled a lot of gunpowder routinely. Gunpowder efficacy was tested in the same way as gold coins. The difference was that gunpowder testers often lost their teeth doing gunpowder tests. This meant that they couldn't test to see if the gold coins were real. This was often why gunpowder testers would only accept well-used gold coins, ones that they didn't have to personally authenticate.
Bitcoin.
