...and then your USB stick has a technical fault and everything is lost.  No way I would rely on one solitary USB stick alone. 

Not planning to mint coins either, that would be copying what others have done, no originality there.

The point that was made about "lots of competition in a slow market", this is a very interesting point.  Perhaps the Bitcoin ecosystem is still to small to launch a profitable product into.  That makes it hard for small-timers like me because often the companies that can launch products are willing and able to sustain big losses in the beginning years in return for getting their brand name out and known early.  Small-timers like me can't sustain any commercial-scale loss.

Well...thats why Im here asking you.  So far its been very helpful.
