Bitcoin is growing very powerfully but in this present scenario which factors can destroy or make its market value Zero.
Nothing. No one can destroy bitcoin! As long as community is here, it will survive.
I disagree with you. It seems to me that the biggest threat to bitcoin is itself in the bitcoin community. Miners can not solve the problem of high fees for small transactions, the fork, the user has turned the currency into a tool for investment. there is no consensus in the community and this is a big problem.
