Bitcoin transaction confirmation depends on the traffic of transactions and fees paid by the bitcoin users. In other words, bitcoin transaction confirmation model is dynamic and varies from time to time (period of confirmation). As of now, there are around 5,000 unconfirmed transactions (which is far better than the situation 10 days ago) but still, we cannot be sure that this situation will remain like this forever so this is one of the characteristics of it.
if the situation will stay better in future, i think we don't have to be worried when we want to send bitcoin to other wallet, i hope that the transaction will be fast confirming so there is no waiting time to long to see the completed confirmation. i am sure that there will be more than 1,000 transaction to be confirmed in a day but if the traffic is not busy and the blockchain is working good, then 1,000 transaction will be completed in short of time and it is good for bitcoin user itself.
