Okay, have increased the price of gas, but who will explain to me why the transaction do not go, I've been wanting to sell a coin on etherdelta many times and can not do it
This is because gas limit is also comparatively low. Also increase gas limit as well with gas price otherwise your transaction will run out of gas.
Understand gas limit and gas price first. It's is beautifully explained here:
To understand the other two components of the equation (gas limit & gas price), take this example:
Let’s suppose you have a car which consumes 1-gallon of gasoline worth $10 per mile. Now, if you drive the car for 5 miles, it will cost you $50. This means that if you need to make your car work (or drive) for 5 miles, you will need to spend $50 by putting 5-gallons of gas into it.
Similarly, to run a line of code or do an operation on Ethereum, you need to burn the appropriate gas limit (like in a car), where each “gas limit” (like the car’s gasoline) will have a per unit price called “gas price”.
To clarify more:
In a car, $10 (gas price) per gallon (gas limit).
In Ethereum, 10 Gwei (gas price) per gas (gas limit).
Note: Gwei is the measuring unit of gas price (I will discuss this further in the article).
Gas Limit
Usually, when one is talking about “gas” in Ethereum, they are referring to “gas limit”. This simply means some amount of fuel is required to execute that operation or run that particular smart contract code.
Gas is a unit that gets translated further into Ether (ETH) as a cost of performing that action (or work). The requestor pays this cost to the miner who actually mines and validates that transaction (or action).
On Ethereum, the gas limit is measured in the unit of “gas”. For instance, if you want to execute 5 lines of code on Ethereum successfully, it will require 5 gas units. Think of it just like your car which consumes 5-gallons of gasoline for a 5-mile drive.
Gas limits are already defined on Ethereum depending upon how much code is needed to be executed on the blockchain for a particular operation.
