ETHW would have a chance, a tiny chance, with a competent core dev team. But given that the core dev team appears to be a bunch of scammers who were incompetent at coding it (they needed outside help/corrections) and listed a bunch of companies as supporters including us on their website without permission I believe ETHW has no chance. Sell it all asap. If it makes you more money to mine then mine it but sell don't hold.
I really wish someone competent had taken over ETH PoW.
