is there any reason for you to predict that in 2020 there will be financial crisis or it's just unreasonable speculation or just say it's just bullshit
I could agree with your point that in few years maybe bitcoin's price will be skyrocketing but talking thing that's not happened yet without any reason is just nonsense

Well, if you look it from the perspective that Bitcoin is available everywhere, in any country in the world, in digital form, than Bitcoin is already international currency.
Original purpose of bitcoin is not to replace offline money but to offer new, revolutionary way of payments online and it's vision for financial freedom and how to get rid from the banks.
So, I don't think really that Bitcoin will ever become ''true'' money and replace some official currency in the world, in any country.

Yes if we find massive adoption in future then it will become an international currency and it will also take price to higher level, but I don't think that it will happen sooner.

No government would ever adopt a currency that's so easily concealed

I think its already been international currency because anywhere you can use bitcoin online but you can not use it locally you can exchange them depends where you are from.. But i think almost world wide are using bitcoin or collecting bitcoin.

Bitcoin is not an  international currency yet , its usage is too limited and  many people are still not aware about, it can be international  currency only when it will be widely  used and accepted.

That is exactly the case, we need to consider. Bitcoin is already being used globally so it can be considered international currency. I am kind of tired of seeing people asking when will bitcoin take over and change the currencies in the world.
Bitcoin and fiat aren't even the same thing.

People are divided about this question, many think bitcoin will become international currency soon, and even more people thinks bitcoin is international currency already. I belong to group that believe that bitcoin is international. All signs are here, people from all over the world are here, trading and exchanging bitcoins in any currency they wish. What we need more, what kind of proof would satisfy people who don't believe yet? Bitcoins can just become more accepted and used in this world.

I think bitcoin will never be international currency because its already international currency online.. and world wide.
because i think every each country know about bitcoin..

I definitely agree with you. Bitcoin is already used all over the world and I doubt any country would declare Bitcoin as their official currency.
