Transactions per second are bound to the block size.<p>The mining groups in China are against raising the block size because of bandwidth and other realistic concerns.<p>The core developers, many of whom are employed by a company that has a business model that has a higher chance of success if bitcoin does not raise the block size, can neither agree that the block size needs to be increased, nor how to perform the increase, nor to what size to increase it to.  Even if they could agree, the Chinese miners wouldn&#x27;t update their software, and we&#x27;d end up with a forked blockchain.<p>The primary places where bitcoin is discussed are moderated by a single individual that considers things like XT and implementations of BIP-101 to be altcoins and actively shuts down discussions about them and other block size increases.<p>It seems to me that bitcoin isn&#x27;t in the process of scaling at all.
