I live in Europe and you can transfer EUR money from one country to another for free; that's progress. But from the UK (in the EU but doesn't use the EUR currency) my bank only allows me to transfer £5k (US$8k) per day to other European countries, and each time I do it they charge me £25 for the privilege (US$40). I had a tax bill recently in Austria (where I live) due to assets held in the UK, I owed £20k. (I have no problem with having to pay the tax.) That took 4 long phone calls over consecutive (business) days to transfer that money, and cost me £100 in total. Imagine if my assets in the UK, and thus my tax owed in Austria, had been 10x as large, or 100x as large.

I have no interest in dealing drugs or hiding income from the taxman. But using banks make things incredibly difficult, and charge huge fees for their trouble. It's time banks got "disrupted".
