So you can see how many times has Bitcoin died so far in its history.

The point that I am trying to make is this, every time the price drops or we have a turmoil in the community or some bad news, Bitcoin dies according to everybody. But oddly, Bitcoin is still alive and well. It just refuses to go!

So to answer your question, don't worry, Bitcoin is going nowhere and it won't die!

Cheers!
