It took me over 3 years to finally get Bitcoin (BTC,) but I did and have tripled my money. But your question is a good one, but I tell friends and family to do some research or let me explain it simply - All U.S. money Federal Reserve note is a Fiat currency, not backed up by ANY collateral like Gold or Silver.

So yes - BTC is a Virtual or Fiat currency.

I'd buy some BTC, make some money and buy silver as the long term investment.
