Goes Up Higher Reborn (GUHR) represents the rebirth of GUH. GUHR is a first of its kind elastic autonomous community token with renounced ownership. GUHR is both contractually guaranteed to increase in price until it far exceeds Bitcoin’s price (based on the BTC/BNB pair). To achieve this goal, GUHR dynamically adjust its supply to achieve an increasing price peg, which begins at $0.001 and increases 5% every 4 hours for 360 epochs, at which point it will peg to Bitcoin’s current market price + 1% every 4 hours.

GUHR.addLiquidity(uint256,uint256) (#982-996) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH.value(ethAmount)(address(this),tokenAmount,0,0,address(this),block.timestamp.add(300)) (#988-995)
Ensure that an arbitrary user cannot withdraw unauthorized funds.
