Banks and other financial institutions fear crypto currency mainly because it can't be controlled by anyone. It only takes two people to create value in something by simply agreeing to trade for it. Value in anything, including fiat currency of any kind is only given value if people perceive it to be of value and can be used to trade services or goods. Crypto currency is a threat to financial institutions because it challenges their monopoly in the marketplace for what is used for exchange in goods and services. They track it through "deposits" and "withdrawals", pay low interest on savings, and use your money to lend to others. They control it and know how manipulate access to it by 'choosing' who can borrow it and when and how much they can charge in fees for "international exchanges". What banks are starting to realize with the adoption of crypto -currency is that those 'fees' go away. It will challenge their fee structures and their profit margins. A classic example of this model is the wire transfer from Euro to US dollar. You go to a bank in Europe, if you've done your research, you manage to find a bank that offers "wire transfer" for 15 Euro. Then they provide you with an exchange rate that is lower than the market rate, earning them more money in the transfer. Then on the receiving end, the receiving bank provides a lower exchange rate. In this example, depending on the amount moved, it could easily cost $30 just to transfer money from Europe to the US. What we are seeing the beginning of the FUD propaganda from banking industry with regards to calling Crypto high risk and will fail. We are also starting to see more "regulation" attempts from governments, which is no doubt fueled by special interest groups (banking industry) to petition the governments to assert some control over its growth and limit the threat is poses to the banking industry. This is just my opinion, but believe strongly that this is what is occurring in our society today with regards to crypto.
