what aspect of bitcoin lacks good functionality OP? you said it has no central control yes and accepted but the functionality here remains unclear to be, but i want to believe you're talking about upgrades or new developments which will let me refer you back to bitcoin improvement proposals (BIPs) which are the current and basic functioning adjustment made on the bitcoin network.


that's why the harder the government keep trying against the network the stronger it becomes for them to control, all this were the advanced measures from the bips to give a stronger resistance against centralization, security and privacy following some set up concesor protocols.
