The creation of blockchain came with possibilities and predictions of a future where intermediaries could be eliminated entirely. It is capable of executing millions of transactions within seconds at a lower transaction cost and requires no centralized authorization.
With the blockchain trend going on as strong as the moment, is it possible that blockchain will replace banks any time soon in the future?

Especially in 3rd world countries with a bad developed banking system, in which many people have no bank accounts, bitcoin and other cryptocurrencies can fulfill a major role when it comes to transactions. Everyone in those countries has a mobile phone. So they only need to download a wallet and can start sending coins to each other.
On the other hand in developed parts of the world like Europe, US and parts of Asia Bitcoin and other cryptocurries more or less fulfill the role of an investment. People are more focused on the speculative aspect, instead of the banking features bitcoin and other cryptocurrencies deliver.
