The failure of the SegWit2x proposal has given more ammo to the argument that bitcoin is a digital gold; however, a better version of PayPal can still be built on top of the base protocol.
The so-called New York Agreement is sometimes credited for bringing the Segregated Witness (SegWit) improvement to the Bitcoin network (others say it was the user-activated soft fork outlined in Bitcoin Improvement Proposal 148), but the hard-forking capacity increase that was attached to the agreement has failed to gain much traction. For that reason, support for the 2x increase has waned and a number of CEOs who pledged their support for both changes have withdrawn their advocacy for the change.
Some have pointed to the hard-forking increase associated with SegWit2x as a contentious waste of time, but there was also much to be learned from the whole experience.
