This is the reason of why i don't believe that Bitcoin will disappear or a bubble as many countries are already supporting Bitcoin with more and more are now considering to support it as they are now starting to draft their own regulations. Hopefully the whole world will accept and recognize Bitcoin so that it can be use anywhere like the US Dollar.
LOL, those people that keep on saying and spreading that Bitcoin will be gone soon or die soon are just FUD spreaders that wanted the price to go down for their own benefit. FUD spreading is already a classic evil move by ill-minded people and this is already happening a lot of time through Bitcoin's existence and you'll find this kind of people on different forums and social media spreading false news.

It's kinda funny to realise that bitcoin is illegal or restricted in most of the "not-so-democratic" countries.
The real problem is the unclear status of bitcoin in the Tier1 countries(USA,UK,Canada,Australia,New Zealand)+the EU countries.By 'unclear' I mean that bitcoin isn't considered a currency.It's still considered as a digital asset.
I guess they have a point why Bitcoin is considered as an asset and not a currency because of its use today, seriously it is not used as a currency to buy stuff on the internet but it is used as an investment medium by people, a speculative asset that favors the speculative trading industry.
