that's normal, people are used to old things and even afraid of new technologies, they used old phone for example for 20 years and they won't go to new phone in days
same with bitcoin, we use fiat for ages now and it will be very, very hard to make people change to bitcoin because it is still new to them
Bitcoin is only for speculation and fiat for real world purposes. Bitcoin confirmations take so much time. imagine people trying to pay groceries in rush hour super market with bitcoin...
Bitcoin has a system that is best, in my opinion the level of confirmation in any transaction is very normal and it will not negatively affect. So the problem of confirmation in the bitcoin wouldn't be bad for us in the future. because it is now experiencing an increase in the number of bitcoin transactions.
If you are talking about the delay in confirmation time then its not a big deal as it will be resolved in coming years, and if you hold coins then you should surely spend those coins.
