The forum must create it's native token and distribute them to members based on their activities.
Tokens must be transferable among forum members but should not be listed on any exchange.
Although the ticker btt is already taken, we can have btf that stands for bitcointalk forum.
Any crypto project planning to run their airdrop or bounty campaign must buy these tokens first from forum. This will give forum another stream of revenue generation.
This will also prevent scam projects from running bounty and running away without paying.
First the Forum must be nothing !
Second , i guess if your Idea about the Token would be coming that means a lot of more data usage as it already is !
And as others already have written there is Bitcoin that is related to the Forum and thats why the Forum exist.
Why should this prevent from Scam Projects ?
If somebody want to scam he will buy the token and doing it , because a lot of Users would be thinking its safe because he bought the Token.
