Maybe bitcoin might end but I'm sure Cryptocurrencies will not. Bitcoins are very controversial and hot topic nowadays. Many organizations are considering to accept bitcoins in future(like banking sector, online retails etc) and simaltaneously there have been some setbacks to bitcoins like chineese government putting bans on bitcoins. So the future of bitcoins is little uncertain.
it just speculation. the truth still hold far way behind to become reality. bitcoin still survived because this community always stay strong at the back of bitcojn so im sure what ever happen bitcoin will live long.
