Here is guide for the Gas price in ETH unit Calculation:
If 1 ETH is $10, 1 gas will cost 0.00000002 * 10 dollars.
If ETH is $10, 21000 gas will cost 0.00000002 * 10 * 21000 = 0.0042 dollars, which is 0.42 cents.
Based on the calculation shown, with the current
ether price (250$) the result will be 0,105 dollars instead of 0.42 cents, which is very expensive in my opinion.
[Q] Is there any miners having
gas price less than the default gas price(0.02 microether)? If yes, what would be the probability for miners having very low gas price to deploy a transaction?
