It is indeed good to hear that banks like PNB are seeing the future in digital currencies. Studying it is a great step meaning they are already preparing themselves into it. It will be an advantage since when they engage themselves with these, the demand on bitcoin will increase and so its value. Other banks will consider this as well, and many trusted companies will be expected to invests more .
It is a sign na nakikitaan na nila ng potential income para sa kanilang banko ang bitcoin at iba pang mga coins, kapag ginawa nila to for sure marami sa atin dito na maeencourage na magopen na lang ng bank account sa PNB kaysa sa ibang mga bagay pa, kaya mainam din yan para mas sumikat pa ang bitcoin sa bansa natin.
