It will be unfair to say BCH is a failure at this time because the end is not yet here for it. Its true that it had suffered some downturn and even currently but beyond that, its also a coin that is prone to up and downs rampant in the crypto industry. For me, I wont say its a failure yet until a lot of exchange sites that provides support or currently providing support, stops and start delisting the coin. For BCG, no one knows for sure if its even going to come around but at the same time its an alt.
