When cryptocurrency started

While the 90’s saw attempts to build digital currencies such as the Bit Gold and B-Money, they were never adopted by enough people and so they faded away. It was Satoshi Nakamoto’s announcement of his Bitcoin design in late 2008 that marked the start of a well-established cryptocurrency era. He was able to solve the one previously intractable problem of double spending. It is widely believed that bitcoin was invented by Satoshi as a response to the world-wide banking crisis of 2008. The very first bitcoin was created in early 2009. The first altcoins started in 2011 with the earlier ones being Litecoin, Namecoin, and Swiftcoin.
