Airdrop Hamster Combat, upgrading the KYC card at level 25 requires 

In the game  a massive investment of 2.61B coins while offering only 633 coins per hour in return. This raises concerns about the efficiency of such a large expenditure compared to other cards that may cost less but offer higher profits. Here are some key points to reflect on:

1. Main Role of the KYC Card:  

   The KYC card is likely meant to be a stable source of long-term income. However, with just 633 coins per hour at level 25, the return seems low for such a high cost compared to other cards.

2. Why the High Cost:  

   – The steep increase in cost at level 25 might signal a significant upgrade, potentially offering hidden benefits or synergies with other cards, even if these aren’t reflected in immediate profit.

   – Games often ramp up upgrade costs at higher levels to balance progression and encourage strategic spending of resources.

3. Strategic Considerations:  

   – When evaluating the ROI (Return on Investment), players would need to calculate how long it would take to earn back the 2.61B coins. Earning just 633 coins/hour means it could take an exceptionally long time to recover the upgrade cost.

This high upgrade expense may make more sense for players with substantial resources. Those with fewer coins might get better returns by upgrading more efficient cards first.

4. Long-term Impact:  

   The KYC card likely provides consistent, long-term profits. If it works in conjunction with other cards or game mechanics that increase overall earnings, the heavy initial investment might pay off later in the game.

5. Exploring Alternatives:  

   Before committing to the KYC card upgrade, players should weigh their options. Other cards may offer better returns with lower upgrade costs, making them more beneficial to prioritize.

This analysis helps players decide whether upgrading the KYC card is worth it or if there are better opportunities for growth elsewhere.
