Im a COS holder along with a good number of Binance related projects holder. No strings attached, I believe in transparent projects, a great team and awesome product like what Contentos got doing.
I think the recent COS price spike shows what happens when a cryptocurrency gets more demand due to its use.
You're quite lucky to hold COS tokens, hope you benefited from the pump. I wish the project considers giving other users of photogrid from other countries the opportunity to earn from the event. I would certainly participate if there's any photogrid event in my country.
Although I'm still doing my research about this project but does it mean that only Brazilians can benefit from the photogrid events? What are other ways non-Brazilians can earn or is it strictly on purchase? Is it intended to be global or confined or simply a matter of time and it will spread out?
