WINNERTAKEALL RULES

The winning price ceiling is set at 0.00013000. The wallet that cross this line with a buy order first, takes the prize pool. Prize pool is made up from 
buy fees and is set at 10%. Winner will be verified by the BUY price as noted on the DEXTOOLS.IO pair. After the prize has been claimed, the token will be liquidated
48 hours after the winning transaction.   

Remember this is a game of strategy - use your buys/sells to outmanouver your competitors.
