🔥 The Apes Ring was forged in the Ethereum Doom when BAYC released APE.

⭕ Ape Rings rules ⭕

▶ If you make the biggest buy (in tokens) you will hold the Apes Ring for one hour, and collect 4% fees (in APE) the same way marketing does.
‍Once the hour is finished, the counter will be reset and everyone will be able to compete again for the Apes Ring.
▶ If you sell any tokens at all at any point you are not worthy of the Apes Ring
▶ If someone beats your record, they steal you the Apes ring
