Here if you want to send bitcoins to exchanges then you must definitely pay the cost, and you can complete the transaction according to your mempool which will be of great benefit. Because Bitcoin Mempool is so important that they provide the right information at the right time, there is no doubt that you will benefit from using it. If you use Mempool then you will save your time and be able to do Bitcoin transactions properly and you can benefit from every aspect.
Even if you believe that you know how to read the mempool or to use wallet transaction fee estimators, you still might end up making mistakes in regards to sending transactions with fees that are either too high or too low.
Look at back ups of the mempool here.
