Hard fork, soft fork, segwit 1,2,3,4,5 can do everything. The bitcoin in your hand can also be split into 10 forks.
its just that at some point in time (for the reasons that i have not yet figured out) people forgot that a change no matter how small and no matter if it is called soft, hard, warm, ... should reach a
consensus!
we were on a very good track not so long ago. if you read the SegWit proposal it is well though, well planned, it needs >95% support from miners then it needs node activation and then lock in and all that.
and so far all the changes have been happening like this. with a set % support, then nodes activation and lock in and ....
but this was
ignored and forgotten at some point.
however this has nothing to do with "decentralization" bitcoin is still decentralized. it is just filled with people who forgot to educate themselves and came in only to make profit.
Exactly! All this has to do nothing with the decentralized nature of bitcoins and it wont be great step towards the prosperity of bitcoins to make them centralized. It has attracted masses just because of this unique feature and bitcoin market cant afford losing investors in huge numbers.
