NOTE: This needs the db to be nuked if you are running a test cluster * updated gas refilling logic to reflect EthFaucet contract * fully dependant on on-chain contract to refill and unlock gas * minor fixes to nonce bootstrapper Ideal Values: INITIAL GIFT = 0.015 THRESHOLD = 0.01 TIME = 12 * 60 * 60 # Sample for 30 txs EXTREME LOW = 0.00675 LOW GAS USAGE = 0.00694605 RISING = 0.0135 HIGH = 0.027
