How risk-averse are you? But even if you aren't, I suspect that right now bitcoins aren't a great investment strictly in expected-value terms due to the high risk that they will decline in value by a lot. No one really knows what will happen, though.
I'm fairly risk averse in the sense that I wouldn't ordinarily feel confident enough in my knowledge to play on speculative markets...I just happen to possess BTC because someone liked something I wrote and kindly tipped me in BTC a couple years ago. I'd forgotten about it for a while, and today realized that it's worth 20x more than it was originally.
So basically my inaction caused me to inadvertently made a good investment. And even though I wouldn't ordinarily have tried investing in BTC, now that the decision to invest has essentially been made for me ...
As in Joshua Blaine's original description (below), but may be used to brag about things you've accomplished either this month (December) or the previous one (November), assuming that you haven't brought it up in any earlier Monthly Bragging Thread.
