You absolutely were wrong. The increase was estimated around 72% when you made your 100% prediction and it ended up being closer to 75%. Not 100%.
Sorry, but according to my math 224k -> 434k = about 100% increase [to be precise 94% something something]. Or, are maths in various countries that different?
Now, who's estimate was closer -.-
The previous difficulty was not 224k. It was 244139. That is a 78% increase.
Yes, and no doubt due to the latency between ordering hardware (when mining appeared more profitable) and getting it online. Judging by the prices at the usual places I would have to say that such expansion is likely coming to an end for now (maybe another week or two of latency some orders, but I suspect new hardware purchases are dropping dramatically for now). So, hopefully the next difficulty increases will be relatively moderate and maybe even some retrenchment in a few weeks. Depends in part on the price of the BTC. If I were AMD, I would be buying coins to push the price and excite orders and them when they are ready, dump them leaving many stuck with too much hardware, wait for the correction and a new product release and repeat.
A far as AMD, you have been warned!
