Yes, I'm looking to scrape up $100 to invest, largely because I'd hoped doing so would give me a tangible difference in curation rewards. But to see it explained this way makes me not want to bother - either investing or curating. Curating/upvoting seems hopeless and pointless now that i understand it better. I might still invest $100 here and there for speculative purposes, but I was thinking it would also pay in curation rewards. Yes, a tiered system to motivate people at $100 - $1K is a greatly welcome idea!
