Amazon appstore is incompatible with iOS . You need an Android platform to use this method . <| sep |> Please explain this science . <| sep |> I am very pro segwit but it really bothers me how the core community dismisses the concerns of thee BU and other big blockers . I get that some of them do come off as crazy but many have legit concerns . I think the easiest solution is just to promise and by that I mean come up with a very clear set of conditions to crease the blocksize after segwit . Most prosegwit people seem to think that of course eventually the blocksize will need to be increased . Why not just embrace that , write down a solid plan for when these factors are met segit , X usage , Y whatever we will increase blocksize put that into 13 . 2 while waiting for segwit to finish , and incorporate that community rather than split it .
