Back in March 2014 the coin was launched via an ICO held on the Poloniex Exchange. As with all Crypto Currency in 2014 the Forum Bitcointalk was where the community first came together. The original thread is still there if you wish to peruse over it. Please note this is NOT the current working thread ! https://bitcointalk.org/index.php?topic=549485.0
The original Developer of Bitcoin Plus went by the handle XBC Plus. Once he received the ICO funds he succumbed to the lure of Barbados (or somewhere similar) and went and had very nice holiday. A team from the Community was formed and 'Took Over' the coin. The wallet was fixed and time went on. And then alas, some of those community members also disappeared with what ever Bitcoin they could get their hands on.
Finally in May 2015 two members of the Bitcoin Plus Community, Egghead and JJMV, steadied the ship and 'Took Over' the coin again. They hired respected coder 'Mammix2' to fix the wallet and add encrypted messaging into it.
The XBC holders at the time were allowed to exchange their coins on a 1 to 1 basis. This was a brand NEW coin on a NEW Blockchain. A new coin had been created. The name BitcoinPlus was kept but this was a new coin in all but name. In May 2015 ‘The XBC Project’ was created to support the XBC Network.
The technical specifications for Bitcoin Plus has changed over time. Originally XBC was purely a Proof of Stake Coin. Current specifications can be found here.
XBC is now entirely a Proof of Stake Coin having previously been a hybrid POS/POW for a period of time. The ability to use POW was switched off at block 400,000 which happened in late 2017.
In June 2017 - The XBC Project hired Bushtar (Lead Developer of Feathercoin) to start developing the XBC Wallet.
In early October 2018 'The XBC Project' disbanded and all XBC assets taken on by Bushnell Crypto Development Ltd.
On 08/10/2018 BitcoinPlus Version 2.7.0 RC1 was released to the world. Read more on our blog.
