Energy SPDR:

I just got a 256GB card and was trying to run it on my pi for that exact function. no luck just yet, i plan to try format it from a Linux machine and try again  

No serious person has had significant concerns about 'blockchain storage' since about forever.  It's been a red herring from day one.  What people are concerned about is access to that storage.  That could be internal (fully verifying a transaction history in the way that Bitcoin was originally advertise) or external (access to high quality and unencumbered bandwidth) should the transaction rate be increased by a large margin.

Pretty sure he's excluding the people you are talking with the word "serious."

You have 10 min and a write speed of 90meg a second with an average block size under 1 meg.
I think the pi will top out at about 10meg a second so it should work as a node.

don't think so ... those walls have been there for the last 2 months, they'll just retreat a bit ... maybe.

And if you substitute the 6 for a 6.3 (and I'm being conservative) to reflect the increased rate of block findings per hour due to constantly increasing hashrate between difficulty adjustments, you get 11.0%. You see what I mean?

Getting through that bfx wall is a big deal. Like I said, there's enough bullish action where the little sellers ought to be getting behind the big ask walls instead of jumping in front so as to catch an extra few dollars  of pop when the wall breaks .
