One way that bitcoin would die would be if another type of online currency became so successful that it makes people completely ignore bitcoin.
One of the other cryptocurrencies that have the chance to compete with bitcoin is their ETH has a remarkable development. And ETH prices also skyrocketed. Maybe in the future ETH will be a tough competitor for bitcoin. And competitors can also make bitcoin die
Ethereum is already a tough competitor for bitcoin and a lot of people now are planning and thinking to migrate from ethereum to bitcoin because of the growth of ethereum that is showing some strength and potential in the long term investment just what like happen in bitcoin and i think ethereum will be the next bitcoin based on the market capitalization and also the features of it.
