With respect, that answer doesn't really provide a working answer. It actually sounds like it does the exact opposite. Within the past couple pages it's been stated that actual Amigas are not capable of running the wallet (unless we get one that's web-based), to say nothing of mining. In point of fact, it sounds as if AGAcoin cannot actually be used by Amigans.
Yes, AGAcoin needs to be updated. It also needs concrete reasons to exist, and what it brings to the market that other coins do not. Not defining this makes the work a technical endeavor, not a practical one. And there is certainly value in honing those skills.
I say this as someone who very much wants to see Amiga and AGAcoin succeed.
Ideas? Maybe a few. Develop new hardware. What does that look like? That's a longer discussion for another venue. I would contribute this way before I'd ever contribute to a Kickstarter.
