Bitcoin will be living longer than us, it is decentralized, government can't kill btc. It will exist forever. The price will keep over 500 usd.
It is already over $500 USD and I don't think it will going to stable at $700 either. I'm thinking that bitcoin is going to be stable up to $1,000 and that is going to make bitcoin hard to be killed. Because more and more investors are seeing that earning and investing with bitcoin is much more better than investing in other crypto's.
