In the virtual world I guess it is, it has along way to go to be the strongest in the real world.
I disagree. What do you mean by "in the real world"? Are US Dollars not from the real world? And if they are why do they give $2,700+ for 1 bitcoin then if bitcoin is only from the"the virtual world"? I think everything which is traded for the USD has the real value and hence it's real.
yes USD is a physical currency and has great value therefore it is a real currency, bitcoin can also be count as real currency because it also has value, but in fact bitcoin has now physical body therefore some people call it as virtual, but I thin virtual is not a suitable word for it I think it is better to call it as digital currency, because we can use bitcoin with the help of computer and internet, so crypto currency or digital currency is suitable name for bitcoin.
I think you meant to write "no physical body" instead of "now physical body", and agree with you that bitcoin is rahter a crypto currency than a "virtual" currency. It is pretty strong compared to other currencies even fiat ones and like deisik correctly said:
The "backing" that fiat currencies receive nowadays is pretty shaky overall
So it would be right to say that bitcoin now is among the strongest currencies in the world.
