I am in agreement with you. Bitcoins are posing big threat to banking business. The emerging unstoppable digital currency is attracting masses all over the world. Especially the decentralized nature of bitcoins is highly attractive for investors. In the near future, the number of banks will reduce drastically in the developed countries.
