@Cailleachian Yes, central banks and governments control the supply of fiat currency but without venturing into lizard territory I think it's fair to surmise we don't know who is pulling their strings. What we do know is the banks do control our money once it is deposited with them. They lend it to other people many times over - fractional reserve banking. We are meant to have confidence because the government will bail us out up to £85,000 if anything happens to the bank. My question is where will all this money come from? Is there enough money to bail everyone out?
Look at capital controls applied in the last decade or so in Cyprus, Greece and Iceland to see how you lose control of your money once you have deposited it.
For instance - in Greece, in 2015, banks shut down for weeks to stop people withdrawing their money, when they reopened there were strict limits of 60 euros on withdrawals. In Cyprus, 2012, as well as limits on withdrawals, depositors with deposits larger than 100,000 euros lost a substantial part of their deposits through a "haircut".
And there is no reason why it wouldn't happen here. I found this article last night in the Independent. Heres how capital controls could soon return to the UK The author identifies three conditions - a messy Brexit, an election and a Labour Party victory which could lead to capital controls and those three conditions now look perilously close to being met.
I keep money in the bank for everyday things but would not ever use a bank as a long term store of my money. I'm not alone in this, a lot of people distrust banks and look for other places to put their money. Gold is an obvious choice (proper hold and touch gold never derivatives of), and I think Bitcoin will in time prove to be a great alternative to gold. Of course, I could be wrong. Its a much riskier store than gold - the upside, if I'm correct, is that the increase in value of Bitcoin will eclipse that of gold's many times over.
