Yes. But a fork might change that. As a current example, the Segwit2x fork that has been announced for 28 December proposes to redistribute Satoshi Nakamotos coins.
I heard about the segwit2x fork,since there are many forks going on with bitcoin , i am not bothered much as i am yet to cash in my other fork coins ,but i did not understand is how they are going to redistribute the coins held by the developer,how can they do that fair and share and if they can take the coins from that wallet how secure is other wallets,they could literally take those coins from any wallet.
If someone is holding bitcoin and he dies,the coins he is holding is lost unless someone gets his private key.
I dont think so bitcoin will be die if bitcoin owner die its a fact that bitcoin is decentralized but its not like this that he is running this currency along there must be a lot of people who are working for this network to promote and owner will also have someone who can look after bitcoin after him Im sure that bitcoin have a head office and owner of bitcoin is also monitoring bitcoin on daily base so I dont think so that bitcoin will end.
