How will 2x fail when it has 90% ecosystem support?
On the contrary. B2X has 90% ecosystem rejection.
The same situation we already had with Bitcoin Classic, Bitcoin XT, Bitcoin Unlimited, now with Bitcoin Cash, and same will be with Bitcoin 2X. Same people stand behind all of those! Some of them even sold out their bitcoins at $450 claiming that Bitcoin is broken and has no future...
What? Stop spreading misinformation. The economic majority behind Bitcoin have agreed on the 2x blocksize increase. They are the vested interests who have the greatest say as to the future direction of Bitcoin. This has already been agreed upon.
We will be getting a block-size upgrade for BTC and Segwit1x can chose to maintain a non-contentious minority chain if they so chose.
You are forgetting the Users, we have the power, we buy the coins, and ultimately we determine the consensus.
The businesses and miners are just service providers, some have deep wallets, but they are not bottomless.
Most importantly none of us will let Bitcoin be controlled by private meetings and agreements in which we have no say. B2X can get the fuck-off my precious Bitcoin.
You are right, users do have the power. They have the power to determine consensus after the decisions of the economic majority have been made. The interests of the economic majority is to appease it's users through making a long term working product which the free market will want; not to intentionally destroy their own investment. More demand turns into more profit for these interests.
If you the user believe the economic majority to be making the wrong decision you are free to go support another project. After all, you hold the power.
