Still looking to trade!
Seriously. If someone offers you $1 take it and be happy.
Just for fun I connected recently 4 of these to a Beaglebone Black running cgminer - all in a place where I have free power. The resulting gargantuan 1,3 GH/s worked there for two weeks, the stats page has shown only 112 months left until I could enter payout queue (having mined then 1/250th of a bitcoin).
So: If you let these mine AND have free power AND difficulty will be frozen until end of time AND nothing breaks...
You will make that $1 in a decade of mining.
