I don't like bitcoin unlimited, it will decrease the price and make it become less valuable, and by making bitcoin to hardfork it will risk all of the investor to go away, this can lead to bitcoin domination to end and cause a lot of investor to lost their money, bitcoin should never being hardfork to maintain the investor trust level
Value is subjective. No one can say it will decrease the price 100%.
The scenarios can be played out like this. Example.
A - 95% of the miners support increasing 21m coins to 30m coins. 95% of the users reject it. Users keep their money in BTC and very little goes into AltBTC. Users fire up their mining equipment and the miners mine a worthless low value coin that very few will buy. Miners will realise the errors of their ways and stop mining AltBTC and support BTC.
B - 95% of the miners support increasing 21m coins to 30m coins. 95% of the users support it. BTC will now mine 30m coins. Crazy it may be but what can the 5% do? Dump their coins?
C - 95% of the miners reject 21m coins to 30m coins. 95% of the users support it. Users keep their money in BTC and very little goes into AltBTC. Users fire up their mining equipment and the miners mine a worthless low value coin that very little will buy. Miners will realise the errors of their ways and stop mining AltBTC and support BTC. One then realise the users do have power over their money and that what create value.
The idea that 95% of the users want to increase the coins from 21m to 30m won't happen because it will devalue their BTC, and users are not that stupid, so don't worry.
Now there is division over BU and Core. Both have made grievous errors. Both are proposing so many changes at once. This is a fundamental mistake.
Core - Segwit, LN
BU - dynamic block (EC), flextrans, sidechain.
Person -
A - Core
B - BU
C - segwit and sidechain
D - segwit and not LN
E - Flextrans and LN
F - Flextrans and sidechain
G - Flextrans and dynamic block but not sidechain
and so on. There too many combination of choices and thus many divisions. Therein lies the grievous errors.
I and many others (perhaps over 80%) support bigger block. Easy to raise 1mb to 2mb. Miners support 2mb in the Hong Kong agreement. Albeit with Segwit. Now that half the miners don't support segwit, common sense dictate that the only proposal on the table that will work is -
Z - raise blocksize to 2mb. See B above and it will becomes this -
B - 95% of the miners support increasing 1mb to 2mb. 95% of the users support it. BTC will now have 2mb limit. Everyone is now happy and the objectors will be happy when the value of BTC goes higher.
This could have be done last year or even 2 years ago. None of us would be here debating.
The moral of the story is that when dealing with $billions, one change at a time.
