Bitcoin is getting stronger while it lasts which can be seen in its price now. However, there are factors which I think Bitcoin will be destroy. First, when the power/internet was turned off because we all know that Bitcoin is dependent on the internet. If that happened and when the internet connection come back again, the value might reset back to zero. Second, the government. They might ban Bitcoin when they feel it as a threat to their economy. Third, when a person or group of people hacked accounts especially those users with a huge earnings. Lastly, if there's a new coin with the potential to be popular to many users.
Agreed, the internet is the most important aspect of the possible destruction of Bitcoin. Governments might be able to try to destroy Bitcoin but if people have access to the web, they will fail. Hackers are a problem for everyone in the world.
