Re: Is there a pattern here?
"If you want to use Bitcoin for tiny transactions, or see it as some sort of massively risky investment scheme, then go right ahead."
"Tiny" transactions are exactly the kind for which bitcoin should definitely not be used. I spent some of mine when it hit £1000* and the transactions just would not go through unless I paid fees of a few £ equivalent. Irrelevant when buying a house, annoying when buying a laptop, ludicrous when buying a pint.
* Yes, I realise what that does to the credibility of my advice.
