Segwit has been in testing since 2015 (not within Bitcoin) and for another few months in Bitcoin (a few versions of segnet and then testnet). It is still being tested.
segwit HAS NOT been running with bitcoin data.
ONLY SEGNET (different chain of data=altcoin)
ONLY TESTNET (different chain of data=altcoin)
BU, XT, classic and MANY others have had publicly released implementations available that anyone can download and also do actually relay, validate and store bitcoin data.. for MONTHS
lastly.. stop overselling segwit as the scalability solution and then in another post saying that segwit is not designed as the scalability solution..
atleast pick one and stick with it.. stop with the bait and switch crap
remember you cant segwit a segwit, so whatever small "bonus" segwit offers.. that it is.. no more.. then something completely different needs to be found
however with the blocklimit you can increase and increase.
and to save repeating myself about the exaggerations and realistic expectations
