Interesting, I’ll watch this tonight. But right now, I think it’s uncomfortably likely. They don’t need to overpower the existing network. Once they have say 10 million to 14 million btc under control, they just start using a subset of nodes running their own validation filters. And only sending txns within their network. If they never spend to an unauthorized address then those coins are effectively lost to the existing/organic network. They use their own chain fork going forward. I guess the original network could keep going, but it would be stunted.
