I'm afraid I'll have to disagree with this statement.. Telegram "play to earn" games aren't paying shit. Following airdrops is like scalping - nothing controls their listing process... It takes years to happen and mostimes, doesn't even happen.
Most tokens now with compatibility in other dex get listed fastly than before actually. They might not be listed on major exchanges but they are indeed can be exchange to other coins or fiat due the help of dex. But it also good to note that trading volume matters, so famous/hype airdrop will generate more income, well, it will still based on number your airdrops on certain tokens.
