Bitcoin 20 year from now? Hmm.. maybe it will stay alive if we all help to protect it from fraud and keep it on a good environment.. bitcoin is good for investment and also we can share our opinion about something! Its a good community. Maybe 20 years from now bitcoin can be one of currency out there.. who knows. That what am thinkin.

i agree with gun control, because you can't just shoot people you hate/not like freely thats my opinion
people who disgreed with the gun control will never understand why. because they never actually be a victim
at my country we got gun control so the radical's cant harms the minority. thats the fact you must accept we need it!

So far there is no tax, but i think some people who willing to be the bit trader will eventually make tax for you, just like my local's number provider.
example: google play pricing around 129idr but the provider taxing u and the invoice u got is around 130idr. thats the way it work!
