Sick of your financial data being used to find out things about you that even you didn’t know?
Sick of usurious international transfer fees?
Dammit, but how do you do international payments without them?
They track my expenditure and keep on trying to persuade me that my transactions are fraudulent, which is very frustrating when, e.g. they reason that last transaction came from a different country was that I was in a different country and please could I have that plane ticket after all I want to go home?
Bitcoin and blockchain protocols
See Blockchains for various non-financial uses.
Bitcoins have a thriving, socially-awkard, tin-foil-hat-totin’ community, but are useful. For example, they are the cheapest way to get money across the border in many places. This has been useful even for me, as a normal non-gun-smugglin’ guy who happens to move country often, and doesn’t like paying a 5% conversion tithe between countries with weak banking ties, such as Australia and … anywhere which is not Australia.
However, my exchange rate when buying bitcoins in Australia has been terrible of late; I’m no longer sure these are a great idea. I ended up paying 8% on my last transfer after all the fees were deducted, which is worse than bank rates. My plain credit card came out better.
Bitcoins have lots of howto guides. e.g..
How to convert bitcoins to/from cash:
Odious company, rather expensive. Not recommended.
Envelope full of cash
Usually illegal, AFAICT. Risky.
Good escrow services? I don’t know, but
