EOS CPU Resource Limits
Exodus overcomes EOS CPU Resource Limits by offering a fee delegation service. This means you will never be prevented from sending or exchanging EOS due to not having enough EOS resources.

The EOS network requires every account to maintain staked resources in order to perform transactions. As the resource needs of the network rise, so do the demands on your staked resources. Particularly the CPU. Your CPU stake determines how many transactions you can make on the EOS network within a certain time frame. Because of the fluid nature of the EOS network, the number of actions you can make on the network will fluctuate.
The fluctuations can differ hour per hour and day by day depending on the demands of the network. As you can see from this image provided by EOSCharge.io CPU Resource Costs are very fluid. This is chart is updated in real time and can be seen here. https://www.eoscharge.io/
You can also add in your EOS account name and see the available resources to your account by percentage available...
...and how many actions you may take at that time.
You can view your EOS resource availability in the Advanced Options of your EOS wallet.
