Card system for cryptocurrency is already available in other countries but in my country, there is no sign that it will be adopted or use soon due to that not many people do use or invest with cryptocurrency. I really like the idea of having a credit card like for cryptocurrency but this kinda removes to why it is called cryptocurrency which is mostly used online and not like a bank. It is an investment which people earn from like a currency but no physical features. If ever cards for bitcoin will be released I'm not sure if I'm going to use it or not.
