I think it depends on the level of spam in the network. Some days ago the mempool was almost nothing, tx all over the network were cheap and fast.
But I guess is like other users said... certainly no one know, the spam theory is not confirmed yet afaik
It is not the miners fees that are killing us, but rather the third party wallet providers charging high fees, when the Mempool is normal. I paid $14 to transfer $2500+ to someone via Blockchain.info. < Yes, I know I should not use them, but I had no choice on this transaction >
This was not even a priority transaction. The priority tx would have cost US $75. < That said, this address had a lot of dust transactions >
Some times, we should just blame ourselves for things like this. ^hmf^
