You do not own BTCSatoshi if you sold BCH and bought BTC. You own BTCSegWit and soon there will be a BTCSegWit2x. These are all different altcoins. Bitmain has ASICBOOST and pays no patent royalties to use it (and it can be employed undetectably which I argue was designed into Bitcoin on purpose by Satoshi). I believe they will roll back BTC to BTCSatoshi, which will drive BCH to da moon.
