Two remarks:<p>- There are a lot of exchanges that don&#x27;t involve direct transactions on the blockchain (buying and selling BTC is nonlimited in terms of quantity or time).<p>- There are many altcoins, claiming to do certain things better such as proof of work or block size etc., however, the most convincing argument for using BTC seems to be the current market capitalization. As such, it is understandable that the Core wants to introduce the least amount of distraction possible, i.e. go against improvements whatsoever.<p>Can anybody please explain why increasing block size would mean more centralization?
