are there any credit cards for crypto currency? and where they can be purchased!

Optimists believe that the rate of Bitcoin in a couple of years (possibly tens of years) can generally reach up to 100 thousand dollars for 1 BTC, but it is only in the future. Personally, I think that this is quite realistic if the governments of the countries can agree among themselves and make it legal.
A favorite counter-argument among optimists is a comparison of Bitcoins with real gold (they are often called "virtual gold"). Remember the demand for real gold. Once $ 300 for one ounce was considered very expensive. During the 2008 crisis, gold rose and reached $ 1,800 per ounce. And what is gold? Than it is provided? It's just metal. Bitcoins are also not provided with anything. However, the potential opportunity to make it an international currency makes for it unlimited growth prospects.
