That token(YTG?) could be swap for real Tangram and be limited to something like 1% of Tangram total supply for example
At least that token would have a real utility not like other tokens and give some visibility to the Tangram project
the token would be not pegged to the real Tangram (in term of USD) because it should be a one side swap
so in function of the price of the the token people would have some incentive to swap or not , swapping a token means that that token get burn so decrease the whole supply of that token and create it's own economy based on the price of the real Tangram
Devs can take like 1% of the supply of that token and use it to fund the development of Tangram
tl;dr : Instead of mining or using a faucet you can just put some money in a liquidity pool and earn a token.
