List of all 13 Bitcoin (BTC) hard forks by the end of 2017. If you held BTC on an exchange or on a hosted wallet service, it’s up to the exchange or service as to if you will be provided coins from a hard fork.
If you held BTC on the date of fork in a wallet, you should have the equal amount of coin in each fork based on the conversion amounts below. Long term cold storage wallets should have access to each fork as well, you do not need to move out of cold storage unless you want to access the fork funds, then you will need to move your existing BTC to a new wallet since the private key must be reused on the fork network.
