As for potentially earning real money, it all depends on the HMSTR token and the airdrop. To assess the prospects, it's logical to compare Hamster Kombat with Notcoin. In Notcoin, the developers distributed NOT tokens proportionally to the accumulated game coins. The more coins you collected, the more NOT you received as a reward. Then, they listed NOT on an exchange via a TON wallet and sold it for real money or cryptocurrency.
Hamster Kombat developers have already stated that the HMSTR airdrop depends not on the number of coins but on “overall player activity” and hourly income. Theoretically, more tokens might be earned not by someone who collected a million coins in a month but by someone who collected 100,000 in three days and actively bought cards. So, they farmed more coins per hour. But these are just rumors, and the exact principles of token distribution among players have yet to be disclosed.
In any case, to earn money in Hamster Kombat, users need to accumulate as many coins as possible, wait for the game coins to be exchanged for HMSTR cryptocurrency, and then withdraw the Hamster Kombat tokens to cryptocurrency exchanges where the token will be listed.
