Currently bitcoin has 53 Exahashes while bch has 3. A 51% attack would need 1.5EH+. That is something that quite a few actors in this space has available. Rewriting or grinding the BCH
Sorry. I hate to sound like a total idiot but could you please ELI5 this topic a little further? Not gonna lie, reading what you said gave me some major FUD 😬
I think the economics deters them from doing so. this decision devalues all of their current holdings as they all compete for block reward, why inflate their own currency?
This is something i've thought about a lot too. If all the miners make a decision, even increasing the coin supply or block reward no one can really stop them, save selling their coins
