My question is, what can the avalon do after bitcoin is no longer profitable? what can i use to mine or sell it to someone to run sha-256 based programs?
1. You can mine bitcoin unprofitably.
2. You can sell it to someone who has very cheap electricity and wishes to earn a few months worth of pennies from it.
3. You can sell it to someone who has "free electricity" who wishes to heat their dorm room substantially for a few pennies.
4. You can mine SHA256 altcoins that are using the same construct as bitcoin and hope that they are more profitable, along with everyone else who has a SHA256 ASIC.
5. You can sell it on eBay or Craigslist and hope someone who hasn't done the math buys it (greater fool theory in action).
6. You can scrap out the aluminum in the chassis, and hang the boards on the wall for art.
