Bitcoin is virtual currency.
bitcoin is not virtual, it is pretty real. please stop using that word for bitcoin.
this topic has some good arguments against these types of words being used to describe bitcoin, I suggest giving it a read:
https://bitcointalk.org/index.php?topic=1733918.0unil now bitcoin nothing real physic
and physic bitcoin only collection can't use transaction
so bitcoin not real curency, still digital curency, digital curency not diference about virtual curency
same with paypal, perfectmoney and more
