In my opinion bitcoin wont die never , the confirmation yeah its takes sometime very low but depends how much fee do you add into transaction . The principle is very simple , if you add a good fee into transaction then you have a high priority on transactions to be confirmed
If you put a low ammouny to transaction fee then you have to wait more days

I usually use blockchain wallet is one cloud wallet , they have automatically fees for transactions and they are confirmed fast

Bitcoin wont never die , the CEO from blockchain and many importants people told in an interview that bitcoin can reaches 500.000€ in 2030
