As long as we are here to support bitcoin then bitcoin will not end because bitcoin is depending on us.I dont think so that bitcoin will end, because bitcoin is gaining popularity day by day.
Yes, we all have to support bitcoin in order for bitcoin to get to the main stream which is the reason why I felt so sad during the forks because it divide the bitcoin community and this is not what we ought to do but evangelize bitcoin. However, bitcoin will never end and the things that can end bitcoin are electricity, miner and the government. Although, some government are in support with bitcoin and some dont while most miner are now mining BCH which cause the dump in price of bitcoin lately.
