the only way to reach level 25 is buy some bundles to get more coins. with real money.
before, someone can reach Tier 25 only use premium at Terzo Festival, but at Terzo Festival, we had Top 1% for All TLE and the box had 1-12 coins.
But since Fxxk, many TLE use Top 100 and the box has 2-8 coins. so no way we reach TIer 25 without buy bundles.
