Yuk;
the 0.15 versions disconnect btc1 nodes and disrupt the network causing propogation delays. No thank you; want to be well connected to many different versions of nodes because its more redundant as some nodes even 0.15 have certain bugs. Your advice is very bad technically speaking.
Can you please clarify the point about 0.15 - in red?
In what way ate btc1 nodes disconnected?
How is the network disrupted?
I'll tell you what I know for now.
Btc1 nodes are the b2x nodes that were recently assembled by their main developer.
After their hard fork btc1 nodes will reject all legitimate bitcoin core and other legitimate nodes, which would not support their 2Mb blocks.
After the Segwit activation this summer those 2 mb blocks are totally unnecessary!
But seeing that they are blocked by the new bitcoin core 0.15 nodes, they have recently created some other FAKE bitcoin Core nodes (their user agents are Satoshi:0.15.0: 1185
Satoshi:1.14.5: 126, etc, see details here for example:
https://www.reddit.com/r/Bitcoin/comments/70jjmk/there_are_already_10x_more_core_015_nodes_running/ ), which impersonate community nodes, but in fact they are all launched by the b2x on servers they lease.
