How to unlock the Easy Money! achievement in Mega Coin Squad - Definitive Guide
It does NOT log as you play, or if you die.
The "Bank X coins" achievements are the only grindy achievements for the game, but aren't particularly awful to grind out. While playing the game for the other achievements, you will likely earn around half of the 100,000 coins you need, meaning that, in subsequent playthroughs, you can focus on extending your time in the levels with the Extra Time upgrade, and the Coin Spawner and Coin Magnet upgrades for easier collection, along with the usual movement and attack upgrades. If you use all of your available time in each level to collect an excessive amount of coins, while still earning as many diamonds as possible, you can easily earn 10,000+ coins in each run.
In addition, you could also play up until Lava Land 4-3 repeatedly with the right upgrades; you could grind this level out for 2,000 - 3,000 coins per play of this level.
Simply play through the game as many times as necessary, banking as much as you can. Once you've banked 100,000 coins, you will have unlocked all 3 coin banking achievements.
