i used to run core, but im worried about the 2x fork and what that means
will the 2x take over existing BTC chain? or will there be separate chain for the 2x fork?
the chain that will be chosen as the dominatn one is that with the most nodes running up. So if you support Bitcoin Core you must run a Bitcoin Core node and accept and check transactions with it.
good luck
Yes. Take an old computer and run a node. Thousands of people should do that. Tens of thousands. Think it over.
