Can Bitcoin remain dominant without offering more utility?
what are you even saying here, what other utility do you want bitcoin to offer? Because Bitcoin is a store of value, bitcoin can be use for payment method, bitcoin can be use for cross-border transactions, bitcoin can use an investment so tell me what other utility that altcoins are offering that bitcoin is not offering? As far as am concern bitcoin will still dominate the crypto space, because I don't know what you are talking about.
Are utility-based altcoins the real future of crypto?
do you actually know what utility is, because I don't how the utility is base on altcoins in the real future of crypto.
Where do you see the balance shifting over the next 5 years?
the balance is shifting now where, because bitcoin has already balanced it from the beginning.
