If you thought it was an arguement and not an observation . I can ' t help you . <| sep |> On Adventure Time , there ' s a character that looks like a gameboy , another character walks in on him sitting in a corner facing the wall and says oh my blob are you playing with yourself ? ! The gameboy turns around all frantic as he was actually playing himself . <| sep |> Leon is Noel backwards . <| sep |> The Bitcoin network functioning does not depend on everyone upgrading their wallets though . If you don ' t upgrade your wallet , it ' s going to be harder to send transactions , but it ' s not going to be harder to receive transactions , and you can still do full verification of the blockchain , and not have to worry about receiving fake money . In a hardfork , if you haven ' t upgraded your wallet , it ' s possible for me to send you money which I double spent on the longest chain but you don ' t realize that I spent it on the longest chain already because your node is rejecting that chain as invalid . So yes , I see your point . But the dangers are not the same . It ' s substantially riskier to be unupgraded in the event of a hardfork than it is in the event of a changing fee environment .
