It's not about the issue of the money they are generating; everything can happen. They can still use people to generate such a large amount of money and still turn out to be scams. They can still use people to generate money and still won’t complete any projects.
Whatever the intent of Hamster Kombat project it is indeed one of the biggest telegram web3 app for now and people indeed looking for the "biggest profit" they would ever imagine to get. People literally doing anything to get the airdrops from using bots, multi accounts etc. It's free of course but if it's indeed turned out to be legit then Hamster Kombat team have to look at those users to avoid any bots claiming the airdrops and at the top.
I think the team are working effortlessly to exclude as many accounts that using bots in mining the airdrop. Moreso the game is built in such a that most of the task can not be performed by bots, from their recent announcement they listed various criterias which more are yet to be listed from which the token will be distributed across based on you performance on various criteria, harmster Kombat seems to be a promising airdrop but however, the end shall justify the means, we are waiting to see the end of the story.
