For this, bitcoin has all chances, but this event, the worldwide adoption of bitcoin as a single currency, will not happen soon, at least 5 years from now. And we have to wait, watch and invest.

And you think 5 years from now is not soon? how do you categorise the word SOON? Because to me 5 years from now is just like tomorrow. So it is happening soon. Bitcoin will soon be the world currency for transactions. Just don't be left behind.
