If you don't admit losing to others, as long as it wasn't bought with money, why can't it be said to be free? The transaction is the core, the airdrop is just a bonus. Do you start smashing pots after dinner? Or can you only win and not lose? I never grind, this planning is clearly from Pinduoduo, the same old tricks. I won't play, and I won't advise others not to play; adults must take responsibility for themselves, and profits and losses are their own.
