With regards to the coinkite attack:

This attack might be more targeted than you realise. We are on the eve of a UASF which may or may not be contentious. All coins moved to a single address. Possible chain split, dump the coins on the chain you oppose for peanuts to the dollar and give everyone their bitcoin back on the chain you support forcing them to be emotionally endeared to the chain you wish to succeed. Your heart is where your treasure lies. This is war.
