Actually, it is just their opinion about Bitcoin will die or not with their own perception, we'd love to share our opinion, don't we? If you disagree with their opinion you can just leave it behind.
but those who think bitcoin will die, they do not understand what is bitcoin ?, how about its history? how is it going? all they know is that bitcoin will die because the bitcoin price drops. come on, fiat currency is also like that, this market is sometimes up and down sometimes.
maybe some countries forbid bitcoin but which thwart bitcoin also exist, we just need more support from those who are not familiar with bitcoin.
