Why does EOS Mining Constantly Remind you about insufficient CPU?

Why Your CPU Resource is Constantly Reminded as Insufficient?

CPU resources can be understood by the concept of the miner fee, when the contract is executed or sending tokens, the CPU resources will be reduced. However, the CPU resources are completely free, and they are not consumed like miners’ fees. They will recover after 24 hours of use. It is obtained by staking EOS. The so-called “stake” is not to sell or lend EOS. The staked EOS can be unstaked at any time without any loss.

How to understand CPU

Taking the image above as an example, let’s assume that the current CPU price is 0.1107-EOS/ms/day, then by staking 1450 EOS, I can get 1450/0.1107=13000 cpu. (Not accurate, just an example that help you understand, the CPU is actually calculated in units of time).

Why does it show sufficient CPU but you still cannot send?

Due to CPU price fluctuations, the CPU resources that are exchanged for staking EOS are also constantly changing. Assuming that the unit price of the CPU is 1, by staking 100 EOS you can get 100 CPUs. If the CPU price suddenly rises to 10, then naturally only 10 CPU can be given. This number is always fluctuating according to the CPU price. In extreme cases, the CPU skyrocketed prices can happen, and with the CPU obtained by staking is not enough to send a transaction, it would show that there is CPU, but it still indicate that the CPU is insufficient.

Example:

Case 1:

Sending a transaction requires 1 CPU

CPU unit price is 1

By staking 20-EOS you get 20 CPU

CPU unit price suddenly rise to 50

By staking 20-EOS, you get 0.4 CPU

0.4 CPU cannot meet the minimum requirement (1 CPU) for a transaction, that is why it indicates the CPU is insufficient.

How to understand CPU

Why does it show sufficient CPU but you still cannot send?

Example:

Case 1:

Sending a transaction requires 1 CPU

CPU unit price is 1

By staking 20-EOS you get 20 CPU

CPU unit price suddenly rise to 50

By staking 20-EOS, you get 0.4 CPU

0.4 CPU cannot meet the minimum requirement (1 CPU) for a transaction, that is why it indicates the CPU is insufficient.

Case 2:

CPU unit price is 1

By staking 20-EOS you get 20 CPU

Using 15 CPU you can send 15 transactions

CPU unit price suddenly rise to 5

With the 20-EOS that are staked can only obtain 4 CPU, but you already used 15 CPU for the last transaction. It will display the CPU exceeds 100% and therefore cannot complete the transaction.

How much CPU do you need at least for mining?

Firstly, mining operation is a process of continuously sending transaction contracts. This process will consume CPU continuously, so it requires a lot of CPU reserves. If you want to experience DApp mining, it is enough to stake 10–200 EOS. If you want to participate deeply in DApp mining, it is recommended to stake at least 1000 or more.

If you don´t have enough EOS, how could you get the CPU?

For average users, there may not have many EOS to stake, you can choose to lease the CPU, spend a small amount of EOS and lease great quantity of EOS in order to obtain CPU resources.
