Maxis saying that the market has already decided that scaling on chain is less promising.
But I think it is too early to say that because the btc fees has been moderate during the bear market. This is because there was less demand for blockspace and also higher throughput with segwit.
Only when blocks are full in btc and fees are high for a longer period, the market will truely decide if onchain scaling or scaling via multiple layers is more promising.
BCH remains a hedge in case that Lightning Network and other Layer 2 payment protocols not live up to their expectations.
