These unconfirmed transactions are going to increase transaction fee which means more profit to the miners. Also this isn't good for bitcoin holders as they have to pay alot of fee.
Yes this is the advantage for the miners and disadvantage for users. now many people do transactions because from last 1 week the price was high and now it is decreasing so people will convert BTC to other currencies. If this takes high fee plus late confirmation means people will scare to do the transaction. If it stuck in the network who will take care?
