so you plan to donate to charities by selling your coins for fiat or how does it work?
including the sale of coins + the sale of various services and goods, the percentage of which will go to charity + donations
It's easy to say that but the actual implementation usually is the hardest part. You are not the first one to promise such kind of charitable act but no one yet proved that they are true to their words. Once they are running and earning good money, such objective was forgotten. How are gonna know that you will stick to your plans?
