also i disagree with bitcoin having "serious" problems. the biggest problem we have is the war itself not the reason for the war. and mainstream is not gonna happen by just fixing these things, that will take a long time and the willingness of people to use bitcoin not just some speculators hoarding it.
I think current confirmation times, transaction fees and general scalability issues are serious problem for healthy mass adoption - certainly for B2C use cases such as paying for things online and bricks & mortar retailers. Otherwise we will have the exactly scenario you mention - speculators hoarding and little else.
because we are very far from that mass adoption i said bitcoin currently has no serious issues. but i am well aware of the problems that you are pointing out and things are moving slowly but at least they are moving forward regarding that.
and as far as current price and the way it is rising is concerned, it is mostly because of new investors that price is going up not because of "mass adoption" or "mainstream adoption" and they don't seem to care about paying $1 fee per transaction to invest in bitcoin that goes up from $1000 to $2700 in 6 months
