Ensuring safety of your Bitcoins after a fork
Bitcoin is managed by its network, and not any one central authority. Decentralization means the network operates on a peer-to-peer (user-to-user) basis. A Blockchain is a decentralized and distributed digital ledger that is used to record transactions across the network so that a Block (a record) cannot be altered later without the alteration of all subsequent blocks and the shared agreement (consensus) of the network.
Soft Forks & Hard Forks
A Soft Fork is an updated version of the protocol which is backward compatible with previous versions. Conducting a soft fork of the Bitcoin software is less challenging on the network as only a majority of node users need to upgrade. All nodes, whether updated or not will continue to recognize new blocks and maintain compatibility on the Blockchain.
Bitcoin Cash (BCH) - August 1, 2017
As Bitcoin gained in popularity, the number of transactions increased and caused delays in processing and confirming them. There had been several proposed solutions to Bitcoin’s scalability issues, but the one that stood out the most is called Segregated Witness or SegWit. In simple terms, SegWit is an upgrade to the bitcoin blockchain that removes some data from the blockchain to free up space so that more transactions can be processed in a shorter period of time. But the opponents of SegWit wanted larger block sizes.

Bitcoin Gold (BTG) - October 25, 2017
After the hard fork on August 1, 2017 that produced Bitcoin Cash, many bitcoiners have been waiting for the possibility of a fork taking place in November 2017 with the "Segwit2x" plan (details below). However, a lot of bitcoin proponents didn’t know about another fork called Bitcoin Gold (BTG) that’s scheduled to take place on October 25, 2017.

Bitcoin (B2X) - November 16, 2017
A group of Bitcoin companies plans to deploy a hard fork to double Bitcoin’s block weight limit to 8 megabytes around November 18th 2017. Known as “SegWit2x,” this incompatible protocol change follows from the New York Agreement (NYA) and is embedded in the BTC1 software client.
