According to @lookonchain, buying exactly at a DEX listing announcement is increasingly unprofitable, illustrated by DOYR trades on BSC where wallet 0xa7b5 paid an extra 6.8 BNB in tips and spent 44.8 BNB to buy 2.55M DOYR but exited for 32.12 BNB, a $17.4K loss; transactions: https://bscscan.com/tx/0x287d076fc6cf33d24920d5fbc53fa9205e5758a1b3a245d3f89193ddc12005c5 and https://bscscan.com/tx/0x1c48dfa8b40364505027ad4278ed83dca91abcd7a9636514afa49eee1d075ea7, source: Lookonchain and BscScan. According to @lookonchain, wallet 0x8A70 paid only 0.794 BNB in gas, spent 239 BNB to buy 28.8M DOYR, and sold for 282.5 BNB, a $38K profit equal to roughly a 15% return; source: Lookonchain and the BscScan links above. According to @lookonchain, 0xa7b5 tipped more yet still executed one second later than 0x8A70, showing higher tips do not guarantee priority in gas wars; source: Lookonchain. According to @lookonchain and the cited BscScan transactions, this case signals a shrinking edge and compressed returns for BSC listing snipes, where execution timing and fee strategy can turn aggressive entries into losses even with high tips; source: Lookonchain and BscScan.
