If proof of stake proves itself to actually work, Bitcoin will adopt it. Migrating a 200 billion dollar network to an untested PoW proposal would be irresponsible.Arbitrarily increasing blocksize without addressing propagation delay and centralization impacts is also irresponsible.Bitcoin has been tirelessly working on the scaling problem in a responsible way. SegWit will allow up to 12t/s. Mimble Wimble and Schnorr Signatures will further compress transaction size and increase t/s to roughly 20t/s. All this without increasing propagation delay (increasing blocksize).Lightning network further reduces the number of onchain transactions necessary.Rootstock adds ethereum compatible smart contracts to bitcoin as a side chain.All these technologies responsibly scale Bitcoin. Your comment implies Bitcoin is stagnant which to me implies you don’t know what you’re talking about.reply PaulRobinson 1 day ago [-]PoS will never be adopted by Bitcoin. The mining pools that have invested in PoW won’t allow it.Every attempt to date to improve transaction rates on BTC have been hampered by a small group of developers who have a vested interest in it not scaling for reasons explained here: https://www.reddit.com/r/BitcoinMarkets/comments/6rxw7k/info…Bitcoin won’t get any of the improvements you hope it will because there is too much money vested in keeping it exactly how it is today.
