I read that the BX2 fork could kill BTC if enough miners followed it. This fork would certainly be a centralizing influence if it succeeds. Without replay protection BTC could be attacked.
Presumably BTG will get replay protection in place and therefore could serve as the new 'real' bitcoin if BTC was under too much pressure. And 'core' and the community thought it was needed.
Therefore it would be sensible to hold the BTGs (whether you like the fork or not) as a hedge against this possible attack being successful.
I've got to say that I only half understand what I'm writing about
but that seems to be the gist of the many, many hours of surfing and reading that I'm doing!
1. If B2X got most of the hashing power then yes it could possibly kill off BTC but the chances of this happening are pretty low it may be a short term inconvenience but the miners will follow the most profitable chain and on launch B2X will be running at the FULL bitcoin difficulty so will need to have a pretty large value just to be profitable for the miners
2. Yes BTG will have replay protection and is due to be merged on github within the next 2 or 3 days as for saying that bitoingold could become the new bitcoin this is highly unlikely to happen but should see huge gains for early adopters
OK What about this?.......
B2x gets launched with a typical pump.
But the pump doesn't stop - Pentagon missing $10 trillion, Fed off balance (missing) $9 trillion. I don't believe everything I read but where there's smoke there's fire. So just saying. One trillion dollars is 10X the market cap of bitcoin or to put another way - about a 1000X the 24 hour trade turnover. Crypto currencies are still tiny compared to the amount of fiat currency in the system. A tiny % of what is out there could make an enormous difference.
So the pump carries on long enough that most miners see the (apparent) light and turn to B2X and the majority of BTC holders get worried and start to sell.
Maybe I"m being paranoid? Having read the reddit discussion about the DCG (main driving force behind B2x) and that one of their directors is also a director of the federal reserve: I have serious issues believing anything that is proposed by B2X can be of benefit to the bitcoin idea of fairness and self regulation.
