Currently, I only know if bitcoin is already widely legalized in some countries, but in some bitcoin states it still has not been legalized, although bitcoin has not been legalized, but the use of bitcoin will not be prohibited. In the future I'm sure bitcoin will be legal in many countries or even all over the world, I want bitcoin to be a transactional tool that can be used offline.
Using bitcoin just being said through offline would really be just a dream.If you mean offline then you are pertaining for it to be used physically which we know its an impossible stuff considering that bitcoin is really just designed to be a digitital currency which means having a physical form would really not happen and thinking off 21 M supply is not really sufficient for it to be considered to have a physical form.Its decentralized feature will entirely be lost.
In our country try bitcoin and other crypto currency is now under investigation and consider as asset and to protect the right and ownership of the investor, they are now looking for a way to make it legal with a law....
You are just mentioning here about ICO or investments which is making some regulation to protect its citizens.
