Still don't really understand how the charity work, does this means the coin will be distributed to anyone or any institution that need for some donation.
I mean, does it get distributed in a form of coins or in FIAT currency?
It will not be distributed to anyone or any institution. Organisations/Institutions, verified by the system, will be eligible to start a funding to collect $EVI.
After they've raised let's say 10M of $EVI, they are obligated to "sell/return" it back to us to prevent them from gathering the whole supply and in exchange for that they will be compensated with, probably for now FIAT(not confirmed) but eventually in the supported crypto valuta once we get to that stage of the cryptocurrencies.
This is the general idea, we still need to work things out on how to approach things, but those will be clear once we release the whitepaper.
