Not really looking like dying any time soon
People focus so much on what the price of bitcoin is that they don't look at *how* bitcoin is traded. Bitcoin is quite interesting because it is the first asset whose trading/exchange infrastructure was created from a clean sheet, and so you have things like 24/7 trading, multiple exchanges, and direct trading with counterparties, that are going to eventually be used to trade everything else.
Bitcoin isn't likely to die soon, 24/7 trading is what attract many people. Bitcoin has gathered a lot of value until now, and this value is rising over the years, so instead of dying bitcoin can just be more stronger, I also need to add that bitcoin has continually beat the odds, and price movement surprise us all sometimes.
Many people are still investing in bitcoin success, and bitcoin will be major crypto currency for a long time. Who knows what will happen in the future, and maybe some other altcoin can replace bitcoin one day, but that is one big maybe, and that can`t happen in near future.
