Why can't they adopt the blockchain. There are a lot of benefits in the blockchain networks which may also increase the financial growth and also the banks would love being amongst the cryptocurrencies. As compared to the start of the cryptocurrencies, there are a lot of members as compared now which shows us the growth of the blockchain network with respect to time.

Time will come when even centralized banks would have been accepted the blockchain networks to make their funds be managed smoothly. Paper money might perhaps get reduced when cryptocurrencies will hit the local markets and I can bet that the world will get more developed once the banks or the government joins the cryptocurrency revolution.
