Weird that I never heard of this. But I guess it's good for the urban poor in the area, they get to profit and they'd clean up the river. I hope it wouldn't be like the Indian cobra scenario though.
Even if this doesn't completely clean the river and bay, they at least got introduced to crypto. After ETH it's just a matter of time before they find out how to use BTC.
I don't think that most of the people in the Philipines know what ethereum isand I'm sure that they don't have ethereum wallets.The project devs are going to pay them with a cryptocurrency that is going to crash and decrease it's price,which isn't fair.Projects that are oriented towards cleaning the environment are always good,but this project won't lead to further crypto adoption.
Then they will find out. The organization is likely going to walk them through the process of making a wallet.
Also, the people they'll include the project likely don't make more than $5 a day, even with a slight decrease in ETH price that amount of money isn't something they'd just stumble upon. I saw kids picking up trash in the river on TV, they'd never be able to earn $5 from doing that all day.
