I want to create a transaction in the main-net. Each transaction modifies 4 * 32 bytes of storage. It also creates a event with 3 indexes and 150 bytes of real log.
Note: I arbitrarily take 300 Euros/Eth.
The calculus made follows:
Cost in gas calculus: Cost TX : 21000 gas/TX * 1TX = 21000 Cost storage : 20000 gas/32bytes * 4*32 bytes = 80000 Cost event : 375 gas/LOG * 1LOG = 375 Cost Topic : 375 gas/topic * 3topic = 1125 Cost byte/log: 8 gas/byte * 150 bytes = 1240 ------- TOTAL 103740 gas gas to Euro calculus: 103740 (TOTAL) gas * 0.000000032 Eth/gas * 300 Euros/Eth = 0.995904 Eu
The 0.000000032 Eth/gas is taken from the average gas price at http://ethgasstation.info/
The final price, 0.996Eu, looks extremely costly, so I'm thinking there is a mistake in my calculus or something else that scapes to my understanding.
I base my calculus/data in next references:
