Slow variable block times, crap UI/UX, crap mobile experience, crap multi-custody, just bad all around. Great for hodling, but not user friendly at all.

Have you ever tried lightning network? I have an nfc card that use lnurl to transact instantly. UI//UX is great. LN solves all the problems you mentioned.
