I don't think Hamster Kombat will continue a good streak, but that's just me. I am pessimistic about it in general 
Me too, I'm pessimistic with the current scenario on Telegram airdrops because too many users are participating and some of them are even teaching others on how to make fake referrals. This is why I am currently seeking projects that haven't been promoted in Tiktok, FB, and instagram.
Grass for example allocations went down after Closed Beta when it has been overly promoted in different social media
A good idea would be to let the community know when the game will end from the get-go (which usually never happens) and do the grading regarding the referrals not from the moment they appear, but more naturally - making the metrics bigger for shillers once in 2-3, or even 5 days, depending on the project.
