In my opinion nothing and no one can destroy bitcoin, because bitcoin is a completely decentralized and peer to peer currency, no one have or can control it. It is a decentralized source of payment system and it won't get destroyed. 
I agree with you too, there is nothing will destroy bitcoin , because of its completely decentralization and peer to peer currency, and when the time will come, it will solve the problems too.Yeah, that's true and bitcoin is getting more and more powerful, so it is difficult for any one to destroy bitcoin, and now its time for bitcoin to rise and not to die.
As days pass by, more people know about bitcoin. And they will use it. This makes it more powerful.
Yeah and for that we need that bitcoin should be promoted on a global level, if the promotion is good, it can attract many users towards adopting bitcoins.
