There have been a lot of forks lately. Bitcoiners never seem to get any peace of mind. That’s how I see it.
Fortunately, most of these forkcoins are worthless from day 1. The recent eCash one is traded at less than $30 on
neoxa.exchange. No need to get into trouble to claim them!
I wouldn't dare use this to prevent replaying on my real Bitcoins. If Bitcoin would accept this in the future, your transactions can still be replayed.
Bitcoin accepts this already. I think what he meant is to create a Bitcoin transaction with OP_RETURN (>83 bytes) so that it cannot be replayed on the Bitcoin Knots chain. (Then you move your Knots with a transaction you verify that is invalid on Bitcoin.)
Yep. More useless garbage.
