Hello,

several times I saw transactions on the blockchain where the average fee shown at memspace is pretty low, like 1 sat/vB, but the paid feed for a transaction is higher than the amount that was to be transferred.

Here is an example https://mempool.space/tx/bd9d7c255bad5a51e09ad535f55b51ab19054489b8e46cc24f47a127a5058593

Can anyone explain what the purpose of these transactions are?
