Valid trading strategy?

2) Hope fork creates 2 tradeable currencies
3) Dump both
4) Profit!

@nvk If you mean that a node can hard fork away from an unwanted soft fork, yes - but action is required on their part to do so.

@bergealex4 Right, from a macro view it’s not traditional governance so much as self-governance overlaps forming a usable network.
@SooMartindale that would fall under devs aiding in bypassing vetoes
@bergealex4 Nodes govern themselves :-)
@bergealex4 From a micro / technical view, all nodes are equal. From a macro view, it certainly gets more complicated.
3 branches of BTC “governance:”
* Full Nodes (can veto miners & devs)
* Miners (can veto devs)
* Devs (can help others bypass some vetoes)

@BitcoinBelle They have a different BTC address, presumably trolling for tips from people who think they are you.
@BitcoinBelle Um, is this an imposter version of you who just popped up: @BitcoinBeIIe
@Truthcoin True, though an activation orphaning attack is functionally equivalent to just lowering activation threshold & forking them off.
@petertoddbtc @prestonjbyrne Yes, but this one is accurately named. Why do you think it’s called “Hacker Gold?” May as well be named “SFYL.”

@TuurDemeester I’m sure there are quite a few people in the court system who wish that SCOTUS could accept more cases.
