The XEmpire team has already mentioned the criteria of airdrop which is wallet connection. Those users who didn't connect their Ton wallets to XEmpire will definitely be out of airdrop's race because their mined tokens will be burned out. There is also a rumor going on that it is necessary to connect wallet and make a transaction to qualify for airdrop which is not true at all. Those who have connected their wallets will get their X tokens based on Total points earned, Mining per hour and Referrals.
As far as transaction is concerned, it is choice based and the one who makes transaction may get extra X tokens. If you have connected your wallet then you must ask and inform to your friends so that they can also be qualified for the airdrop by connecting Ton wallet with XEmpire. The price and profit is not in our hand, it's all depend on token allocation. Even if price is low but users get generous tokens they still can earn good profit.
