Amiga dot Com is worth much more as a Portuguese/Spanish dating service than as a technology company. Any bankruptcy sale would result in the domain name being sold for several tens of thousands of dollars and the company and technology for a few cents. Amiga Inc have registered AmigaInc.com, so they may have contingency plans on selling the domain name to keep functioning.
Amiga Inc. does not own the word, "Amiga." They own the trademark for the use of that word with respect to technology. If someone else wants to come up with a brand of chocolate bars and call them "Amiga" or a new shampoo called "Amiga," they may lay claim to such a trademark right now without paying Amiga Inc. a penny.
For better or worse, I think the Amiga trademark still has quite a high value. I would sell my house for it, but I have a feeling that I would need about 10-20 more such houses!
