<snip> bitcoin needed maximum adoption to get recognition and since it is a decentralized system that is not controlled by a centralized authority then it will become a more reliable place or a safe heaven for people to invest their money. and that could only be the way adoption will increase. </snip>
On point right there. A decentralized system cannot be adopted immediately like a centralized one which could simply be implemented by a decree from an authority. And we ain't seen nothing yet as far as adoption is concerned. We're still at the tree level height but certainly destined to hit the stratosphere and beyond.
