people are selling because btc/usd jumps ?
I don't know. Nobody seems to be commenting on business-related reasons for the stock's diminishing popularity. As far as I can tell nothing major has changed to the way the business runs nor to its popularity with players since it was commonly traded in the high .007x. I see no reason to lose confidence and follow suit selling at what seems currently to be very low to me.
I guess we'd need time with the usd/btc in the new range to see whether the influx of new money coming into bitcoin that took the exchange rate so high is reflected in a corresponding increase (relative to USD) in the amount bet on SD*? With as crude an instrument as watching the SD bets go by on blockchain.info I have no reason to believe it is different. dooglus's magnificent data and charts don't either give me reason for concern on that front. The recent losses don't tell us anything new so my only conclusion is SD investors may on the whole be a bit more fickle and SD considered as a less long-term-thinking reasoned investment compared say to other betting stocks on the stock market?
It is not much more difficult to own SD shares than it is to play SD so thinking about it that way may generate lots of interest in part-ownership when stocks are on the rise and there's a buzz about it then when all the excitement is back on the usd/btc side with SD plodding along doing its thing with a few more losses than average and maybe it's simply losing interest.
* Sorry, I didn't word that very well. What I'm wondering is if the amount bet in BTC can stay constant or increase despite the increase in exchange rate.
