In , uh , Most Places , obvious price mistakes like this are not binding contracts for the seller . <| sep |> Eat a dick you stupid bitch <| sep |> Even if 2 MB is acceptable , and it probably is , it should not come about before segwit as a hardfork . Hardforks are dangerous . And there is no need for it once softfork infrastructure is in place . Also , with L 2 protocols such as lightning enabled by segwit , onchain traffic may very well take a cliff dive . Or at least be diminished for a while . We would need to live in that world for a while before being able to determine what the blocksize should be . I think 1 MB quite possibly may be enough even in a scenario where bitcoin takes over as the future world reserve currency . If that ' s the case we ' d be pretty stupid to have 2 MB blocks going all that time .
