this kind of question are not really suitable to answer because this will only add Fud in the market and also I love seeing positive thoughts that negativities. and why would people here may think of Bitcoin going to zero when almost everyone here loves trusting this coin and here to invest and gain from it?
We shouldn't ignore questions like this, we should be more concerned with questions like this, which are Fuds for us, are silly questions because we already know a lot about bitcoin. But for newbies, who don't know anything about bitcoin, these questions always haunt them, and they need our help to explain it. The people asking this question are obviously interested in bitcoin, but since they have a lot to worry about, once they figure it all out, they will have the same faith as we do.
