Do you think Bitcoin will become the first world currency for buy and sell ? 
of course bitcoin has been traded, this is as you ask. but if for many online stores there aren't many stores that can use bitcoin transactions. the main factor is that the value of bitcoin is very unstable.
bitcoin will not become the world's common currency. There are many reasons.
1: blockchain technology used by bitcoin is 1.0, and the world is approaching 3.0
2: transaction fee is too high. We can not buy a bitcoin cake and have to pay $ 50.
3: The number of acknowledgments per second of bitcoin is too small. does not meet the . may take several days,
All this shows that bitcoin can not be the world's common currency
