That was a very shortlived Bitcoin rally.  Price is almost back where it was.

Wonder who got that one.  What a winner.

What are some of the best 2nd-hand mining rigs at the moment around the 100usd mark?

Do you guys think that BTC may have found a new support level around 330usd?

Has anybody seen what's been happening to the BTC price lately?  Yikes!!
Does anyone have any theories as to why this is happening?

Why does the Bitcoin system allow for blocks with 0 transactions? 

Sometimes I worry about the environmental impact caused by mining.

Every time a disruptive mining technology enters the market, the mining equipment the rest of us holds gradually becomes useless and ends up in landfill a couple of years later.  There's probably already tens of thousands of PCBs in landfill from us already.  x86 or ARM-based motherboards can be re-purposed some of the time, but these ASIC boards cannot.

I'm a newbie but I understand it this way.  When we solve a block, we solve a math equation whose difficulty is artificially inflated.
It's artificially inflated so that blocks are not solved too quickly, and hence maintains the systems integrity.

Over the last 1-2 months, what has been the average block finding time on Slush?

Hash rate is now at 4.8 watcha-call-its.  For the last couple of weeks it's been hovering around 5.6.

The most common type of post here tends to be the "verbal diarrhea" type post; the ones with little to no punctuation.

It's over, ladies.

Newbie here;
Invalid block == orphaned block?

12 and a half hours on that block now..... annoying.

^ Thanks!

Do you folks know if there's any ARM board cheaper than the raspberry pi which can do the (allocating?*) to my miners?
I am happy to make a filesystem, do the cross-compiling and whatever.  But 50USD is kinda expensive for a single-board computer which only needs to run a very small footprint program.

*(what's the correct term to use?)

8HRS?!?!  What's with this long-ass block?

So the difficulty decreases sometimes?  I was under the impression that it only went up-and-up-and-up.
How is the difficulty set?  Is it set by the number of leading '0's required for a block solution?  Who sets the difficulty? Is it the nodes?
