I think those that are worried about 10 minute confirmations are mostly people that don't use Bitcoin very often. "10 minute confirmations!?! WTFOMG!! I won't wait that long at a fast food restaurant!"
transaction time != confirmation time
Bitcoin is faster than dogecoin and litecoin because of the amount of nodes.
That is correct. I've just recently used a website in which the transaction was almost instant. This is because they accept the transaction as soon as it gets relayed; no confirmations are needed.
They take some of the risk depending on what kind of services they provide.
A faster confirmation time would not hurt, if we do not make it too fast.
I fear this would have a lot of consequences. I'd rather we did this slowly, from 10 to 8, from 8 to 6 or 5, over the years.
This would be much harder too code. Either the developers try coding all of this in a single try or we would have to fork multiple times.
This is because a lot of things need to get adjusted for Bitcoin to have the same supply over time.
