A Twitter user @CivEkonom has accused largest cryptocurrency exchange platform Coinbase of spamming the blockchain system, thus making the pending period longer and commission higher.
The user noted that after the platform had stopped Bitcoin withdrawal, the volume of the mempool (total number of all transactions awaiting verification) began to decrease. However, the volume resumed its growth after the withdrawal had been launched again.
According to @CivEkonom, the platform conducted transactions separately instead of packing them together, thus making the pending period longer and commission higher.
Commenting on the post, Head of Coinbase Brayan Armstrong said that the platform was working on packing transactions, introducing the SegWit protocol and other solutions to the problem.
