We measure our impact by # of litter pieces picked up and token price. Both have increased steadily. For # of litter pieces picked up, we picked up ~25k litter pieces in Year 1 and we've already picked up 50K+ litter pieces in Year 2. Our biggest bottleneck for completing more litter pickups is funding so the Gitcoin rounds really help out. As for token price, our initial ICO token price was $1.00 and since then our token price has risen to $1.28. We've been able to both fund litter pickups and raise our token price by 1) building a strong community that is reluctant to sell their LTK because of their strong belief in the potential of the project, 2) investing into revenue-generation projects like our community farm in Nigeria.
