Don't be naive, Sushi and YFI didn't got on Binance for free, this is what CZ or Binance employees says, but is not what really happens behind the scenes.
Binance is asking between $250000 and up to $15 Millions depending on the project, to get a coin listed there, even tho is not a upfront fee.
I say the YFI horde, namely erc20 tokens which are made similar to the name YFI and they reproduce fast and buy and sell on uniswap thus increasing their trading volume and so easy to enter into large exchanges, many cases are seen until now and people are trapped in there
