/* Hi fellow etherscan vagrant, idk whats up with the state of defi right now but
 * Yesterday I deployed YURU, idk what happened with that. No promotion, no sharing, no announcement, just liquidity, I held initially 99.99% of the supply, people bought
 * I just did it for fun for no reason:
 * MEVs fucked everyone, generated $1.8m in volume
 * EDIT: You guys have 100% slippage MEV bots took 99% of real user buys on YURU.
 * Anyways I sold some of my tokens to make back liquidity, deploy txn costs, and some profit
 * Why? I believe I'm not obliged to maintain such a random, ERC20 deployed for no reason. I didn't tell anyone to buy, nor forced anyone to buy.

 * also congrats whoever is looking at this you are a true degenerate wtf :)
 * Fucking around on mainnet is so interesting
