It is reiterated by this creator time and again the tapping, swapping and holding mini-games aren't designed to rain millions of dollars upon you, they, however, subsume a blend of boons and bans in terms of financial assistance.
The solutions follow as:
Lower Your Expectations: this is the first and golden rule of gaming! The less the expectations, the more rewarding the rewards would seem, and you would probably say: "that's much from what I expected"!
Try other options: just like Hamster Kombat, there existence humongous number of mini-games in queue for your fingers exercise. Diversification drives dollars to your door.
Avoid thumbnails and always do your own research: Hamster Kombat's distribution trickle down has been carried by pseudo standardized experts, boasting the followers their millions are on their way.
Fair or otherwise, token's distribution is done! Just like millions, you can't do anything except accepting or rueing.
In sum, minimize expectations and diversify the directions.
