Q: What can I do with SCC?
A: You can keep it or transfer it as a usual ERC20 token. It has no other use. But maybe one day it will become cryptocurrency lottery tickets or Santa will thank you with a nice present some day next year.
you have a chance to promote your token, but you didnt and make people think thats your token is a joke.
Q: What will happen with unsold coins?
A: Santa will keep them for himself.
and youll dump it when somebody try to purchase the token ? i mean you can say youll burn it or something.
I think you're missing the point. The token will probably never have a value, its the same type of project as the Useless Ethereum Token which you can see here:
https://uetoken.com/It's just a bit of fun that's all, albeit with a target to raise 125 Eth (approx $65,000).
I've bought 10 Santa Claus coins purely for fun and they will never increase in value or be able to do anything.
