Thanks for the links.
Could you please clarify how to interpret the graph on https://cash.coin.dance/blocks/thisweek, which shows 90% mined by Other. I don't think it actually is a single miner, just a category grouping all other miners.
Actually, I don't own any BTC nor BCH. Moved my BCH to litecoin.
