Hi - I've started looking into Banksy coin recently.
OP say's
Premined coins will be donated in various giveaways
That's a lot of coin to giveaway. Wouldn't it be better used for buying up good artwork on the site, or even used for buying promising artworks outside of the crypto world. Maybe that is the idea but the OP is not clear on that. I am sure some artists just starting out would sell their works quite cheaply and maybe in a few years they would be quite valuable if the artist gets successful.
