Well I just woke up (working late shifts this week) and she was already up and about. She fetched me a cup of tea and I told her I'd been up late and showed her a new Electrum wallet I'd created for her with the wallet.dat in her name, containing 1.00996667 BTC. I'd bought 1.01 in case some of it got sucked up by transaction fees.
She seemed quite happy with the GBP equivalent but a face of mild concern about having money in this new thing she doesn't fully grasp

I said, "See all those extra decimal places? If the price goes up you can use those to buy something nice and still have 1 left.". She said if the price goes up she'd put £300 of it back into her savings, where it came from. I guess she still doesn't see it as a currency in its own right. She's gone out now, she's happy enough and might change her mind about it being a viable currency if/when she gets to use it.
Before she went she let me use a double dildo on her whilst letting me piss in her hair.
^That last bit's to keep Gingermod happy.Lmao
Anyway I think she meant when the price increases by a large enough amount (whatever she thinks is large enough) she will cash out just enough to have £300 and still have bitcoins left. That way she does not have to care about the future value of bitcoin or the risk of losing her wallet or something, as she will have her £300 back.
If bitcoin gains in value even more later than she will have 'free money' as anything beyond the £300 she has withdrawn would be extra money. In my opinion this is a very smart move of your wife and you should not discourage such behavior.
