Long before Bitcoin existed, people were already thinking about digital money. They wanted a way to send money online safely. Many early experiments tried to make digital money real, but most of them did not succeed.
1. eCash (1983)
In 1983, David Chaum created eCash, a digital money system. It allowed people to send money online without revealing their identity. In 1995, he started a company called DigiCash. But most people and banks did not use it, so it failed.

In 1998, Wei Dai proposed B-money, a system for online cash. It was designed to be anonymous and controlled by no single person. The idea was smart, but it was never fully created.

At the same time, Nick Szabo proposed Bit Gold. People had to solve cryptographic puzzles to make money. This system never launched, but it inspired Bitcoin later.
