Bitcoin's value is being held up by investors and traders, but its use as a cryptocurrency, the only thing it was actually supposed to be, is dwindling.
I don't think Bitcoin is dead though. There will always be a way through this because if miners feel that people will give up and stop doing transactions, that'll be an incentive to actually sort out the network by implementing SegWit, which I do believe will happen eventually and Bitcoin will become scalable.
You're right though, for now, Bitcoin is pretty annoying. My transaction with over 3mBTC of barely 10mBTC took over 2 days to confirm. This is not the consistency and professionalism that a great network like Bitcoin should have.
Bitcoin blockchain was true and annoyed many of the bitcoin fanatic but in the end they still support it. Even many times happened that the transaction is delayed most often even you payed a higher fee sometimes its unavoidable it is still it takes an hour before it confirms. And my experience was 2 days almost before it confirmed to my wallet.
