Given the fact that bitcoin is legal in UK the banks has now refused to offer services to exchanges hampering bitcoin uses in UK limited to few number of citizens. It is now reported that bitcoin can no longer be useful to the masses in UK when they can no longer convert their bitcoins to fiat. The reason probably that led to this is the banks are losing profit due to increasing number of people placing their savings on bitcoin rather than on banks. The banks probably feels the pressure and threat brought by bitcoins thus to stop the competition it is the best choice for them to discontinue banking services to bitcoin exchanges.
Whaaat? No way! Do you know how banks make profit? They make it by lending out money to borrowers who pay the banks back with INTEREST. Bank deposits are not really needed these days, you know why? The fractional banking system, that's why.
