I can't 100% relate every good initiative coming from banks to Bitcoin putting a heavy load of pressure on them, but I noticed that in the last few years, the fiat related payment platforms have become much better. Not only do people enjoy instant and free transactions, but banks have shifted from being a bank operating from a distance with barely eye for their existing customers, to banks operating for its customers.
Nearly every month a new bank related ad pops up on tv showing how people can easily and instantly transact with each other. They can send money via email, sms, app, facebook, etc. If you take all this into consideration, then more than ever before, the need for an alternative local currency as Bitcoin, will only decrease. If I am completely honest, and look at all this, then I don't see a reason for the average joe to use Bitcoin as local currency instead of their own fiat currency.
I will give you two reasons, just to start this discussion: 1. Banks are centralized - They can be easy targets for global hackers, who target these institutions daily. < via their weak point, the uneducated customers > 2. Governments control banks, and political decisions have previously influenced people's access to their money. < Take Cyprus and Greece as an example > They can take or block your money tomorrow, and you will have no say in the matter.
We can discuss the other reasons, but these two are very important. ^smile^
Truly it disrupts the financial system and will change how it works. As of now, they are integrating or creating their own system, it affects the remmitance system also.
