To that e-mail, I would reply with citation of other items they have stated but not followed thru on in their 'news releases', including project completion by the 15th, weekly updates, etc.  If they are going to consider their news items contractual terms, then what about the other terms they are violating?

Also, make clear you are a consumer, have no business license, and have not at anytime acting as a business.  That's a fradulent claim on Alpha-t's part, but if you don't disgaree you're accepting their terms.

Their "hardware" can be used for personal experimenation too, no?  What if you are a hobby developer that wanted a scrypt miner for other purposes then mining Litecoin?  Sounds like consumer activity to me

(Just my opinion, of course.  Certainly not legal advice.)
