Nobody could really blame you for that. It took me a lot of research to understand why it was much better, technically. However, that's not always enough, the better technical option can often still fail. I didn't think Bitcoin Cash would overcome the initial negative propaganda and I expected it to get dumped down to $100.
I think the delay in Coinbase and other exchanges actually crediting people their Bitcoin Cash is actually going to reduce how many sell it. Might have worked out well for BCC!
